I've been working through these videos before setting up a small system for my patio, and I'm realizing that this is basically a super-sized version of the biologically stable planted indoor aquariums I've kept for years (my largest has been self-maintaining for about 5 years now). That is very reassuring, as I was a bit worried I'd end up over my head. Fortunately, I'm already all stocked up with water tests and a working knowledge of the nitrogen cycle, and these videos have been the most clear and informative aquaponics how-to's I've come across on KZbin thus far. At this point, I'm giving serious thought to adding a small sweater-box grow bed over the top of my 60 gallon livingroom aquarium for an indoor herb garden since I have a couple extra full-spectrum grow lights that can be suspended over the top and a bag of expanded clay bought for potting my orchids, and it would give me a chance at a cheap trial run at rigging up my own pump and bell siphon before I run out an buy $500 worth of equipment.

Nice one Cristia. Hope the systems grow some great tucker for you. Happy growing. 🐟🌱🍅

[@matansegman4718]

My #1 Mistake was choosing small diameter pipes. Although in theory, my chosen diameters are fine and my system works well, I have no leeway for enlarging the system, and I am on edge in case of minor blockages. My most common problem is with the solids lifting outlet, if it gets even slightly clogged at the bottom of the fish pond the discharge is barely sufficient for the inflow and my fish pond can overflow (kicking off the refill valve of the system and wasting a lot of water...). Anyway thanks for the Video.

[@RobsAquaponics]

Hi Matan. Are you using a "T" fitting at the top of your SLO? I've found that it allows the water somewhere to go if the base gets clogged at all. The base in ours only blocked up when we had netting over the base of the SLO when fingerlings where in the tank. Having the "T" at the top worked a treat at allowing the water an alternate path out to the filters. Hope you can sort yours out mate.

[@chrisharvey3075]

What diameter pipes are you using? I'm about to start building mine with 40mm...

[@uprightfossil6673]

Another great video. As a wise man once told me... "if you start your day and your plan B won't get you there on time, you are already late." Same with being prepared.

Rob, this is one of the best videos I watched on aquaponics online - fairdinkum! By the end of the video, I feel like I could have a system running successfully by the tips you shared. No, I am not saying I will build one LOL. I am saying that you are a natural teacher. You explain the whole thing so well, that someone like me with zero experience about aquaponics gets it. Thanks for sharing your expertise in the subject matter. You rock, my friend.

How are the raft beds growing Matt?

[@mattdawson7055]

When i give them the time and keep on top of adding supplements they are ausome....but atm they look like a shaggy dog that hasnt been washed in 2 years, current focus is getting the fish to harvest at the end of summer then itll be shut down and revamp. I purged 12 bigger fish over christmas they were beautiful, because i had so many fish i had to grade them. I turned 1 600L raft bed into a 2nd fish tank which now has 32 small/medium and 66 big are in the 1000L tank, the 66 will be 500-600g by winter but i may need to keep the small/mediums over winter, as you know just gotta see how we go.

[@charleskiplinger9904]

Great video Rob, really enjoy them. I built one of the 12V air pump backup systems you showed. Works like a champ, but one thing I did discover is that a diode is needed inline from the power converter, otherwise you will feed 12V power back into the electrical lines. Electric folks detected a good 12V about 100 feet down line at a transformer.

[@RobsAquaponics]

Hi Charles. Wasn't aware that would be an issue. Thanks for the heads up.

[@jmkm88]

Thanks Rob, it’s a good reminder to get some air sorted for my blue drum chop and flip in case of power outage

[@RobsAquaponics]

Good idea mate. 👍 Cheers.

[@juglore]

I had made a blue barrel chop and flip aquaponics set up. I had bought the media and done a water tight test. I had set it up on my apartment east facing balcony. I had explained to my fiance that I had to cycle the system and then maybe get 3 goldfish. Then I took a nap. When I woke up from the nap my fiance had gotten excited and gone out and bought 6 plants and 24 small goldfish. Within a week we had lost them all. I still find naps somewhat dangerous but she hasn't done that to me again yet.

[@RobsAquaponics]

Ouch.... Have you popped more fish back in there?

[@juglore]

Hi Rob, greetings from the UK! I love your videos and you’re a real inspiration to someone just starting out! I don’t know if you’re still checking comments on old vids, but thought I’d ask, do you have, or could you make in the future, a video just about the failsafes and backups that you have? Things like securing pipe work, how often you check it, what float switches or backup power supplies you are running, etc. It would be really useful as I want to get the safeguards into the design from the start! Cheers!

[@RobsAquaponics]

Hi Jono. Am having a few weeks off posting clips & answering FB & email messages just so I can catch up with you KZbin comments. 😉 I have a clip on the air backup system but that's about it. kzbin.info/www/bejne/aGK7mKiker6bqsU I run through other bits & bobs on the general update clips but will look at creating one on fail safes & the like in the future. Thanks for the suggestion mate & have a top one.

[@RJ_S_182]

I know not to use carbonate based rocks as a medium and the issue regarding PH , But im not sure why though , if you PH is neutral , the carbonates will stop dissolving , why would pH keep rising then ? I would think that it will jump around between neutral to slightly acidic ?

[@RobsAquaponics]

Aquaponic system water normally turns acidic over time due to the alkalinity in the water being consumed during the nitrification process. If carbonate rocks are used, they will get broken down by the lowering pH, which in turn adds more alkalinity to the water, which also raises the pH faster than the nitrification process can consume it. Not a bad thing for most fish species but can be a real issue when it comes to nutrient uptake by the plants as high pH will lock out most elements at some point. Hope that helps.

[@RJ_S_182]

@@RobsAquaponics Ah , got it , so by the time the reaction stops the alkalinity has increased too much , basically a lagging effect. sorry , fixed my original post to medium , not media :-)

[@Blxz]

My biggest problem was levelling the ground on bare soft dirt. The growbed is towards the back half of the sump tank and the hundreds of kilos has caused gradual compaction to the back left with the bell siphon on the front right. Results in hair-pulling frustration and continuous tinkering to get a non-level siphon to initiate and break reliably. And the only permanent fix is to slowly undermine one side of the foundation of this 1 tonne+ fixture with a trowel and hope it doesn't crush me.

[@Antipodean33]

I did a aquaponics course many years ago and saw a couple of set ups. My question is this, is it a cost effective way of growing food, as by the time you factor pumps, containers, media, plumbing bits and bobs, fish and testing kits etc, plus on top of that electricity, does it come out as a financially viable alternative to other methods of food production?

[@neraphruneblade7903]

I'm about to get started in this as well, plan on having my first set-up built within the next weeks and inside this month it should be operational. I think you need to view the cost of the system as a "start-up" cost and you shouldn't really allow that to color your view of the whole system. Aquaponics is a self-contained, self-regulating system, in general, and while the cost is higher than more traditional in-ground gardening or farming, the flexibility and sustainability of the system needs to be taken into account. It's a down-payment on not really needing to have grocery bills anymore.

[@RobsAquaponics]

It definitely is if you're wanting to grow fish for protein in the backyard. They just don't grow well in soil.😉 There would be much more cost-effective ways to grow a few heads of lettuce if that's what you're focussing on.

[@LamWilliamLamWilliam]

I am about to start an Aquaponics system for the fish pond using the using the water media to grow the plants. After looking at your video i have decided to use a solid media on the trays. We have access to perlite, Coconut coirs, even coral stones. What is best for my media?

[@RobsAquaponics]

Perlite could be an issue in a large bed as it's so small & light. It won't offer the best drainage. Coir would have the same issue in a large bed. They may work OK if y=used in individual post that sit in a try or trough that has a small amount of water flowing through the base though. 👍 I wouldn't use coral as it would have a high level of carbonates & will affect the pH of the water over time. Hope that helps some.

[@raghudp]

[@johnarizona3820]

Excellent points! The problem with over abundant waste is precisely what we are seeing in off shore fish farms. Massive dead zones are getting worse every day. Native species are becoming sick and dying. We have got to stop farming fish in the ocean.

[@RobsAquaponics]

It would be great to see more terrestrial fish farms where the "waste" is used in regenative farming. Am also hoping to see more insects being used to create fish feed to help take some pressure off the oceans as well. Cheers John

[@JaxCopper]

I am just starting my chop and flip 250 gallon IBS aguaponics system. I have 2 questions. 1) I am using expanded clay pellets, do I need to put something in the water to help produce the bacteria to change the amonia to a nitrite-nitrate? 2) Can I use plant nutrients in this system, or do I even need to?

[@RobsAquaponics]

Hey Jax. The bacteria will turn up by themselves but you will need to add some form of ammonia for them to feed on. I have a cycling clip that walks you through the process if that helps at all, kzbin.info/www/bejne/oZ7bl3yVm9CgqsU Some folks will add fish friendly additives like kelp/seaweed extracts but generally speaking there is no need to add extra nutrients into the system if the fish are well fed. The only exceptions being calcium, potassium & sometimes iron as they may not be present in a great amount on the fish waste. I use calcium hydroxide to buffer the system & the kelp powder I add has a geed deal of potassium so they're covered. I will add some DTPA chelated iron from time to time if I notice deficiencies in the leaves. Hope that helps some.

[@TheSDBeast]

Sorry I'm late to comment, but I hope you see this and get a chance to answer. In your explanation of overcrowding the system with too many fish, you gave a breakdown for the amount of media required to grow out a fish to one pound (6.6 gallons of media). If you were going with a larger fish that you wanted to grow to say 2 or 3 pounds, or maybe even larger, how would you convert the goal weight of the fish to determine the correct amount of media needed for your system?

[@RobsAquaponics]

You can use the 1lb of biomass per 6.6gal of media as a rough guide. 👍 From there you can also work backwards if you want to use smaller ornamental fish as well. Cheers David.

[@Aquaponic.Atheer]

Halo pop is also there in the event of water evaporation and continuous compensation will affect the height of the ph

Not really as the water is continually being topped up as required & most contain some form of alkalinity. Rain water can be problematic though as it is normally mineral deficient. 👍 Cheers & have a top one.

[@thomaswolf9297]

Hey Rob, I have an indoor pool pond set up in my basement (460g total, currently half-full) with a custom 50-gallon radial flow filter with multiple filtration phases. I've run aquaponics with bluegills in the past, but am now running 100% pure strain Blue Tilapia (Lakeway Tilapia Hatchery). I had no problems establishing a very active breeding colony, and have 150 juveniles I don't have enough room for (I've had to do daily water swaps on a 20g; it may be euthanasia time again) and I had to kill about 1,000 fish so far, though none have ever died from water issues - unless you count 2 jumpers before my tanks had lids and had established the nitrogen cycle in the beginning. So, I have endless fish and I want to set up a DWC system for lettuces and a bell siphon media bed. Here's my problem. I have a rash of aphids from ordering some red wigglers that came with unwanted guests that I cannot seem to eradicate. I've kept their numbers down with sticky traps and am considering an indoor bug zapper. I started a bunch of seeds in rockwool for hydro/aquaponics (I am set up for stand-alone hydroponics as well), and have an outdoor organic soil garden. But, I am fearful of another rash of aphids, especially as my plants are sprouting. The problem with putting the pool outside is that my backyard is not level at all, and I've put too much money into my setup already. Do you have any input on how you would deal with this if you were me? I'm very close to having a permanent food source that runs smoothly. Any input is appreciated! I tried neem oil as well and that didn't help much!

[@RobsAquaponics]

Hi Thomas. Are you seeing any ants on the plants as well? If so they might be farming the Aphids & if you can control then then you've won half the battle. The most effective way I've treated outbreaks is by blasting them with a hose. Might not be very practical with your set up though. Manually squishing them may help reduce the numbers if the plant is large enough. Have heard of folks getting good results with food grade diatomaceous earth as well. It didn't do much on a large outbreak we had here but might be more effective on smaller ones. Spot spraying with horticultural oils on a regular basis is a method others will use. CAUTION must be taken not to get it into the water though as the oil can coat fish gills & suffocate them. Hope that gives you a few ideas to try out mate.

[@thomaswolf9297]

@@RobsAquaponics I haven't seen a single ant. Only aphids, spiders and the rare centipede. Sticky traps have proven most useful so far but since they survived an entire package of them, neem, soap and garlic spray, hand-crushing, manual plant removal, etc - I went ahead and ordered a $40 bug zapper off of Amazon but it hasn't arrived yet. I may give diatomaceous earth a shot as I want to use some with my red wigglers anyhow, but for now I am thinking sticky traps and electricity are the winners. Next issue: I need a purging tank for about 20-25 full grown blue tilapia..and I don't have one. Lol Love your videos, by the way.

[@pby1000]

Could the waste be collected and used for plants outside the system? Maybe take some water from the system and replace it with new water. It seems like it could be calculated how much water needs to be replaced over a given amount of time. What are the problems with doing this?

I use the solids waste to feed other gardens & have at times used system water to water pot plants. The water gets replaced during the weekly top up & as long as the fish are well fed there shouldn't be any issues with lacking nutrients.

Rob, quick question. Why are you using the clay media over using gravel? The clay media is too expensive where I'm at and gravel costs literally nothing. I do not have an aquaponics setup as of yet (in the planning phase), however, I do have a small aquascape that I plant edible plants in the gravel bed. Is the clay media that much better, and how so?

[@RobsAquaponics]

Hi John. There's nothing wrong with rock other than the weight needing to be taken into consideration whjen planing the grow bed stands. 👍 I went with the clay as I had leftover from our old hydroponic days. We were a bit better off financially when I started the system & the Aussie $ was strong so I was picking up bags for around $20 each which also helped. I would recommend you test the rock for carbonates so you won't have issues with spiking pH down the line.👍 Hope the build goes well for you.

Trout prefer cooler water so I'd probably keep them by themselves XP. We don't have bluegill & can't keep tilapia here so I'm not much help sorry. You could try asking in a group like Aquaponics Anonymous on Facebook. facebook.com/groups/245708769126433

I'm building a smaller aquaponics system with a limited budget for a school project (I have a ~25L grow bed and a ~20 gal fish tank) and I plan to grow just a few gold fish and lettuce, cucumber, and spinach (since they grow faster). Because of the coronavirus I won't be buying the fish for a few weeks, or until we get back in school. Would you say I need to worry about many of these issues, especially dealing with fish waste? I don't have any kind of filter or bacteria to manage the waste, since they're only baby goldfish and not full sized table fish. Also if anyone has ideas about how to feed the fish on weekends that would be greatly appreciated.

Hey Nathaniel. The fish wast can be collected by placing a sponge under the inlets at the grow beds. easy to clean every day or 2. Fish can go a fair while without feed so I wouldn't be too concerned that they don't get any for a few days over the weekends. Sorry it took so long to respond.

Hello Rob. Thanks for putting your heart into all these videos. I have a question about the back up: Are you familiar with the Uninterruptable Power Supply (UPS) that are used in offices to power their computers when the power drops? If there is a power interruption, the UPS automatically turns on and keeps their computer from losing their work. Do you think one of these UPS would be a good back up for when the power goes off in one of our systems? I mean to use one in my system to protect the fish from air pump interruption. What do you think?

Hi John. I was looking at getting one for my parents system but the batteries in most aren't large enough to run the pumps as long as I need them to. I know larger ones are available but out of my budget for the time being. Cheers mate.

Just out of curiosity would an airstone in or in the line to the grow beds fix or act as a fail safe to prevent the degradation of the nitrogen cycle?

I have seen folks do that Zachery but I don't think it's necessary myself. I also like to use the flood & drain method for irrigating the grow beds so that helps add in a load of air & O2. Cheers.

How feasible is operating an aquaponic system in a subtropical climate such as in Charleston, SC? Even with a greenhouse in the winter months and heater for the fish isn't there a real possiblity that bacteria will suffer greatly from temps in the night that get into the 30's during those winter months?

[@RobsAquaponics]

We're in a subtropical climate here in SE Queensland Australia & are having regular lows of around 1.1°C / 34°F over the past week, way lower that the perch like it. The water temp is staying at about 20°C / 68°F due to having a 500w heater in the fish tank. As a result, the bacteria have only slowed down a little as the fish are are only eating a fraction of what they normally would. There are also folks that run their systems a lot colder as they run trout in our colder states here & they don't have issues with the bacteria dying off. Hope that helps some.

[@williampkerr]

@@RobsAquaponics Very helpful indeed. Thank you. We get lows in that range as well. Albeit not many days in a row very often. What about keeping the fish tank temp cool enough in the Summer? Our temps in the summer are low to mid 90s. Is styrofoam insulation ok?

[@RobsAquaponics]

@@williampkerr It depends on the species you'll be using I'd say. I think Tilapia can handle water temp up to about 85-90°F / 29.5-32°C from memory but you might want to double-check that. The fish we use like water temp up to 93.2°F / 34°C so we don't really worry about insulating. It takes about a week of 104°F / 40°C to get the water up in that range I've found.

[@evidencesuggests1697]

Thank you sincerely for all the information you put out in the world!!! You have inspired me to become self sufficient and try to grow all of my own food. I've watched almost all of your videos and have learned sssooooo much from you I feel like your apprentice. I started off last year with just one small one bed, 1 fish tank system but didn't use a filter or block out the sunlight from my fish tank or grow bed and the hot Florida sun grew me a giant algae bloom that decimated my entire system. Well that turned into a hot mess;) anyway this year you have inspired me to build a much bigger system (10 grow beds, 3 fish tanks, a sump tank and a solids filter) I triple painted all of my grow beds and figure to block most of the light out of my fish tanks with pallet wood siding. Can I get the filtration I need with a 5 gal bucket filter??? Is it possible to grow freshwater shrimp large enough to eat??? Can mussels be used in the system as a filter too??? If you and the family ever want to visit Florida, I have a airbnb in my backyard separate from my house that you could stay in;) i could donate the rental fees back to you for some personal advice;) it would be a dream to have rob bob walking around my back yard giving me pointers on how to be more sufficient and efficient!!! Anyway thanx again, your my hero,and have a wonderful day!!!

[@RobsAquaponics]

Hi ES & sorry it took so long to respond. A 5 gal bucket would be suitable for a small chop & flip IBC style system but nothing much larger. Sizing for the filter body will depend on flow rates from the fish tanks as that will dictate the retention time of the water required in the filter. The longer the retention time, the more solids will fall out of suspension from the water column. I'm not sure on the shrimp varieties you have but folks here in Australia do use the native red claw crayfish, which I think you folks have over there as well. 👍 They might be a better option as they grow & reproduce well in aquaponics. I have seen folks include freshwater muscles in their sumps. They are a bit like worms, they will consume some solids but will also produce solids that can't be taken up by the plants. I have also seen that the larvae from some muscles need the gills of fish to complete a stage of development but am unsure which varieties so you might want to look into that as well before selecting a variety to try out. Hope that helps some & thanks for the generous offer as well. B & I would both love to visit the State at some point. The UK is first on the list as B wants to visit her ancestral homeland of Scotland first. Cheers.

[@wallofstar]

Regarding the oxygen issue when pump fail, is it possible to use flat tank with large surface area on top which allow more air/oxygen to dissolve into water?

[@gueto70]

allot of surface with vary few fish, maybe.You need to break the surface tension on the water to allow o2 transfer at any real rate.The wind across a pond doesn't add o2, the waves do. Bubblier in the water column adds some but the bubbles popping on the surface adds most of the o2. Lost power in a bad ice storm.All the stores were closed with no power.Used a 8 inch DC fan pointing strait down at the water running on a car battery. Wind sent ripples across the surface.Juggled recharging batteries with truck but it worked for 4 days.

[@RobsAquaponics]

The stocking density would need to be very low if you were just relying on the exchange of O2 at the surface. You're much better using some air stone, venturi or some form of water agitation at the surface to help facilitate the exchange.

Hey rob. Just been getting into the idea of aquaponics. I don’t have a place in my backyard with good light for plants. The spot i can put a ibc chop and flip system is in the shade. I was thinking about growing duckweed to the feed the jade perch I will have. Do I still need to have 25l of media per fish? I will be using gravel from the local hardware store.

[@RobsAquaponics]

Hi mate. It's best you stick to the 25L per fish when first starting out. 👍 Once you feel confident that the system is working well you can up the limit a bit but I wouldn't go less than 20L per fish in such a small system.

If your fish die from pump failure or nitrate problem, is it safe to eat them, or will the meat be poisonus in some way?

[@johntexan4165]

Are you certain they actually died from this? Also, even though the water looks clean, it still has a host of bacteria present. I wouldn't recommend eating any dead fish. Personally, I would grind it up and add it to the compost pile.

[@RobsAquaponics]

I wouldn't like to say due to legal reasons sorry mate. 😉😅 I do know folks that have eaten fish that dies over night after cooking them very well. I used the dead fish from the thumbnail of this clip as tree fertiliser as I didn't want to risk it. Cheers.

[@bitrick7872]

If I have both a moving bed biofilter and a clay media bed, will that allow me to stock more fish than just with the clay media?

[@RobsAquaponics]

The extra biofiltration can help increase stocking densities. I would still only stock 1 fish per 25L/6.6gal of fish tank volume though. 👍

[@jbl2270]

If the ammonia is secreted through the fish gills, how can a quality food benefit the system please?

Are you asking how ammonia is converted to nitrate for the plants to use? As well as some plants are very good at utilising the ammonia directly, it is mostly the media bed bacteria that converts ammonia to nitrite and nitrate eventually.

[@jbl2270]

@ I was wondering why would someone want to use a nutrient rich fish food if the plants use the ammonia from the fish gills. Would the fish waste just be accumulating in the filter with no added benefit to the plant? Cause I am looking to buy a spirulina fish food on my next purchase. Thanks!

@@jbl2270 Because nitrogen or ammonia is not the only thing needed. Wee need most other minerals for plant health and that is locked in the fish poo hence the use of mineralization tanks. Plus direct ammonia utilization is not really efficient. Therefore we need most minerals as well as nitrates to feed the plants.

[@jbl2270]

@ already! Somehow the plants will use the nutrients I suppose. Thanks for the input. Much appreciated

[@RobsAquaponics]

As Gürkan mentioned above, the plants need more than just the nitrate that the ammonia is converted into. It is also best for the fish to use nutritious food as you will be eating them as well. A sick animal isn't as nutritious as a healthy one. Cheers. Cheers.

Well, this explains why I have trouble with my farm every year. 1. Wrong grow media. I used pea gravel. Don't do that. 2. I have little to no solids filter. I tried making a "swirl filter" where the water would come in and swirl and the clean water would be skimmed off the top and solids were expected to fall to the bottom. Only thing is, it doesn't work like expected, so. . . little filtering. Don't do that. . . put on a good solids filter. Unexplained fish dying off. I lost half my fish overnight recently. This video showed me why. At the beginning of the season (my garden is not in a greenhouse) the plants go nuts and produce like crazy. But later in the season, the leaves turn yellow and production falls way off. Most likely due to one or several of the errors listed in this video. I will be changing the grow media and revising the solid filtering to get the crap out (pun intended). My grow beds must be washed every season because of the muck that gets in there caused by insufficient filtering and capture of the muck. I learned more from this short video than I have from many others! Thank you!

So do your DFMEA! Lol. After watching I am thinking about making a trough for all the suction side to drain into in case of failure. I had a gravity fed system a while back where the tank drained slowly into a ditch which had the grow media then was pumped back... Terrible design, went on vacation and of coarse that is when the pump failed and I came home to dry fish. Lesson learned: always assume a pump will fail. Do you think it would be an issue to make a huge tank with less beds used? I'm a northerner and it gets to be below -18C yearly. I was considering making my tank deep, like 3m deep with a 4-5m circumference. I was not planning on a lot of fish at first but I want something more likely to self regulate the heat. I'll be building up as time goes on and more fish are hatched but don't want to upgrade or make new tanks, just lengthen my greenhouse.

[@RobsAquaponics]

One issue you might have is solids removal from the base of the tank as it's fairly deep. It could also be a bit hard to check if the water gets a few tannins in it from the fish feed. That's would be my main concern Joe. Hope that helps some mate.
