I'm happy! 🤠👍 I've finally been able to get your aquaponics guide! I have been playing with several hobby 'ponic systems for a while (thanks to mainly your videos), yet I have much to learn and this guide is great for referencing. Thanks Rob for all the work you've do putting this resource together; and continuing to add to it! 🌿😃🐟 P.s. If you are considering adding a sand bed your new setup in near future, I'm very interested! Any more info/insight you might be able to share in addition to the videos you already have about sand use, would be awesome. 😊 Cheers! 💖

[@RobsAquaponics]

@@NicoleCChoque Nice one Nicole. We are hoping to have a few sand beds in future builds. One as a stand alone & in another as part of the filtration.

[@SkookumBeehives]

I got my guide last week, and I can attest that it is the single most valuable source of aquaponics that I've found thus far.

[@DanCarlyon1]

Thanks Rob! To anyone reading this Rob's Aquaponics guide is really good, it covers everything you need to get started and takes the guess work out, I can't recommend it enough!

[@RobsAquaponics]

Thanks Dan. I'm chuffed that the guide has helped you out mate. Happy growing. 🌱🐟🥬

glad you have done this video Bob this is something that I will be copying at some point for a smaller system I have planned. I finally made the leap into aquaponics as a school project and I have built a system with bio media and settling tanks but I utilised the bottom halfs of my ibc tanks for solids filtration and moving bed bio filter as it created a neat looking system.we have basically made 3 chop and flip beds. I was having issues with the media getting stuck in areas of the tank untill I fitted a water pump to create movement, it seems to mave worked well. each of my filter tanks are around 300l each. The thing that I noted with the solids settlement tank is that the waste drops out of suspension really efficiently without a radial flow setup. also to help with any anaerobic issues I have fitted an oxygen feed into the tank. it has been a bit of an experiment but it seems to work really well . everything is gravity fed from the fish tank to the sump. I also have connected my bio filter tank in such a way that it almost doubles the capacity of available water for my pump in the sump tank . I had an issue with my grow bed volume when flooding and draining could leave the pump dry without plumbing the system this way. it would be interesting to hear your thoughts on what I have put together. love your videos Bob and your farm looks epic

[@RobsAquaponics]

Hey Michael. Sounds like an interesting system. Any chance of you doing a tour video for me to suss out? 😁 I had a vacant drum at the end of my RFS & Bio return to the sump on a previous build & found that it acted as a settler tank for fine solids that made it through the other filters. Cheers & have a top one.

My guy you make aquaponics look so easy, im new to this i dont exactly know what you would use this for but its always good to learn. Keep putting out the info we will soak up what is necessary 🎉

[@RobsAquaponics]

These aren't needed in every system but can help in certain situations. 9 times out of 10 all you'll need is a decent media bed for biofiltration. Cheers and happy growing

[@iandre8163]

@@RobsAquaponics lovely it's been a while somebody actually replied to me from KZbin land. You are one of the ones definitely. I would love to look through your book but I live in the Caribbean far cry away from 42 Walibi way Sydney. Could I buy it on Amazon and do you have any other recommended reads

[@reginald9410]

Great info,great beard! Thank you, I'm learning so much from your videos.

[@RobsAquaponics]

Glad to hear it mate. Beard does need a trim. 😉

[@zombi3907]

I can't wait to start my next aquaponics setup. I lived in Hawaii when I did my last one and the weather made it very easy. I am learning more about temperate climate growing through winter and debating having a system inside a greenhouse or just finding better winter crops. (I don't like eating Kale, for example :)

[@RobsAquaponics]

"I don't like eating Kale, for example " You're not the only one. 😉🤣 A greenhouse would be the go if the ground freezes there I'd say. Home the build goes well for you when the time comes Zombie

[@xthemadplumberx7110]

I feel like I’ve seen this video before. I use k1 micro, it flips around better, with just air. I don’t know if my biofilter is doing anything for my system, but it’s part of the cool factor for sure.

[@RobsAquaponics]

You have seen bits of it across 4 or so videos. This way it's all in one. 😉👍

[@ZanaCoulibaly-s2u]

Good morning, I enjoyed watching your videos. I have questions how do you calculate the size of the bioreactor? Thank you

[@tk422-7]

Tank uniseals, thank you!

[@RobsAquaponics]

I've found them to be very useful & save a load of coin on the builds. Cheers.

[@ahandymanishere]

Good evening, and thank you for your videos. I would like to know how much cubic feet of K2 Biofilter media you recommend on one 75ga?

[@SailboatDiaries]

You are amazing! Thanks so much

Hope it helps SD. Have a top one.

Thanks / Obrigado

[@SkookumBeehives]

Could you do a build of one of the Barrel-ponic systems, but find a way to include a bio reactor and a SLO under the garden beds? I've been toying with this in order to improve the overall health of the system, but I'd love your expert input and how-to on it. Also, not for nothing, but every time I see your bio reactors, my first blush reaction is "Wow, why did he fill that thing with pasta?" :)

[@garyash4823]

how do you workout how much bio media you need by weight as its sold by weight everywhere i have seen (i will be adding a 2000ltr tank soon)

[@RobsAquaponics]

I've only seen it sold by volume here as far as I can remember Gary. The makers site might have some weights for certain volumes listed if that helps any. Or, you could be creaky & ask a store to weigh a bag of theirs & see what volume it corresponds to.

[@JMFuller227]

Thanks for the video Rob! I’m hoping to start working on my aquaponics setup (someday 😂) and I’ve found your guide super helpful! I did have two hypothetical questions for you: first, would it be possible to recycle plastic old soda and milk bottle tops as MBBR media? I don’t imagine it would work as a 1:1 replacement but are there specific reasons why recycling something like that would not be a good idea for that application? Secondly, would it be possible to make a radial flow settler out of an IBC tote? It would be far too big for any system I would make just getting started, I just happen to have enough totes that I could eventually try that and it makes me curious. Hope you’re well, the farm really looks like it’s coming along!

[@RobsAquaponics]

Hey Jeremy. Bottle tops have been used but they don't stay as buoyant as the proper media. I have seen them used in a trickle type bio filter where the water runs over the top of them to be collected at the base & sent out to the next component. They also collect a good deal of solids in that situation & need a good clean regularly. I've also seen IBC's used as solids settlers, mainly set up with stilling baffles in them rather than as up flow settlers like the RFS. They would take a fair bit to clean out I would think. Thanks mate & have a great one. 😁👍

[@duplessis2006]

will all kinds of pasta work as media?

[@RobsAquaponics]

for a short period of time. 👍😁

How much micro plastic that it produce? It not good for the live stock and the people who consumes it

[@RobsAquaponics]

This is the same media that sewerage water is cleaned with before it is let loose into the waterways or added back into the drinking water supply. It has been engineered to be more stable to take the constant tumbling. I have spoken to folks in waste/recycling & they have told me to be more concerned with the plastic packaging that everyone's food comes in than media designed not to breakdown doing it's job. Cheers.

[@st33ldi9ital]

More like microplastic generator.. no thanks. Test produce and soil for microplastics, I'll wait.

[@helives2630]

I wondered the same immediately. Not trying to be negative, just don't want microplastics if I don't have to.

[@RobsAquaponics]

It would be interesting to see. The only thing I can say is I've seen no degradation after using some of this media for 10 years. It is also the same media used commercially for water purification.
