The ONLY thing you NEED for a CRYSTAL CLEAR POND

[@justkerry173]

I swapped the sponges in my filter barrel for 3 sizes of rocks and I'm absolutely amazed at how clear the water is now. I first found one of your video's a couple of years ago so it took me a while but worked a treat. Thanks Kev.

[@Ozponds]

Well done 👍

[@darcieclements4880]

As a biologist, it is delightful to see a KZbinr that understands pond ecology and is giving actual good advice ❤. It is exhausting seeing over manufactured artificial plastic systems being pushed while sitting on the sidelines jumping up and down yelling "adjust you ecological balance with micro habitat zones and well selected maintenance organisms!"in my head. "Noooo, not a giant empty drum with a plastic box in it ... No, no why are you cleaning the filter weekly, what are you doing?!" Lol.

[@robertbaker3174]

​@darcieclements4880 Hello,Darcie. Having the day off, I was grazing the internet and just found this. A water feature has been on my bucket list for a while, and I may be able to do this soon. Having kept planted fish tanks and some success with raising some fry, I am aware of a bit of this biological process. I found a book several years ago called Dynamic Aquaria. It was mind-boggling to verify the complexities of nature. Anyway,I had a lace plant seed and sprout over 90 plants. I have never been able to reproduce that. If you have any suggestions as to where I might find some information, I would appreciate that. Thanks.

[@glenpryce]

Good tip

[@thecluelessoutdoorsman916]

With my experience the sponges don’t clean then waste more of harboring it in the filter. The rock solution actually cleans the water which I’m throughly pleased with.

I'm glad I found your channel years ago. The detailed breakdowns and instructions were super helpful. I was able to build a bog filter in 2021 that was 6feet x 3feet and 3 feet deep. It flows out through a wide stream and is an absolute powerhouse of a filter that I only need to clean out twice a year. My pond water is always crystal clear, all the fish are healthier, and tons of native frogs populate the bog during springtime and breed in its shallow waters.

There is another way to have clear water I use. I go to local stream which is overflowing with invasive pond weed, pull out large amounts and throw them in water and they filter it. These need to be changed once pond gets cloudy. Your way is by far superior though.

I think of the bog filter as part of the pond. Yours are just as lovely as the pond itself, and that is my goal - to make my bog filter a beautiful functional plant growing part of the pond. I'm trying out a couple different plants this year, I've got hydrocotyle tripartita, bacopa, water sprite, and rotala. I hope the hydrocotyle will take off and shade the top of the bog a little, plus it is so interesting to look at. I haven't had much luck with water sprite in the bog, but it grows like crazy in baskets in the pond, maybe I will have better luck with it this year.

[@kramelbbiw]

​@@heartbeatbandke Pump from pond to a *very* large bog filter. Have water return by gravity via pipe or steam. Gravel in pond & steam should be very small - more surface area for bacteria. Have lining for steam way bigger than the steam - that way the steam also becomes a bog filter. Small waterfall/drop from steam into pond gives audible indication of flow rate (and adds oxygen). The key is both the pump and the large bog filter.

[@laurelscott4466]

Thank you so much, Kev. I’ve just discovered you & although I have a small pond system, it wasn’t working well. I’ve been scratching to find a solution Brilliant, now I know which way to go. So grateful for your generous sharing of I formation. Torquay/Vic.

[@davidhirschhorn2960]

Very nice info. I had an aquarium running similar to what you describe for years. The biological filter was a course sponge that would fill up with bacteria that oxidized the ammonia to NO2 and NO3, which can be consumed by either algae or larger plants. The trick to grow plants and not algae is to add a source of iron. I would add rusty bolts or nails in a plastic mesh bag, which slowly dissolves and adds iron. My guess is that the brown rocks in your filters are adding iron. The second trick is to clean the sponge every month or two, to prevent the bacteria growth from plugging it completely.

The fish are very happy , and Ive just noticed a few baby koi living in the bog filter. All good. Will slowly add smaller natural stones. , pea gravel and plants. But fir now , though half comolete. It seems do be doing a very good job. Perhaps I will build larger systems on my large plot of land up in the Javanese hills and open a koi farm. Why not ?

[@MrJamesdeanhunter]

Hi Oz Ponds! I built a bog filter in my goldfish pond in a 55-gallon food-grade plastic drum. The whole process was super simple, following your instructions, including the open overflow fitting just above the waterline, (as you explained, to prevent a back suction that would drain the barrel in case of a power outage). This has dramatically improved the clarity of the pond water. THANK YOU SO MUCH! However, within a month, I noticed the volume of water drilling out of that open connection increasing significantly, indicating to me that the large to small rocks were getting plugged up wit silt increasingly blocking the passive circulation through the rocks. I tried backwashing it out the bottom valve, (installed according to your plans with an elbow down from the drain valve. to about a 1/2" above the bottom surface of the barrel, but little silt had accumulated there; little came out with the water. A week later, I drained it again, this time going down the silt rocks from above (I KNOW< likely washing away much of the beneficial bacteria). Within a month, the open anti-siphon overflow began again to increase, like before, so I blocked the overflow, (cancelling the intended anti-siphon feature) forcing all the pumped volume of water to be forced through the layers of rocks, before draining back into my pond. Will this negate the beneficial effectiveness of the bacteria-coated stores? Is it normal for the anti-siphon to increasingly bypass circulation through the rock layers? Is my top layer of rocks too small, (I used two bags of approx. 3/8" decorative stones). Will the bog filter still work optimally if I force all the pumped water to circulate up through the rocks before draining back to my pond? I see many small holes across silt that covers the surface of the finest top layer of stones? I'd appreciate any thoughts.

[@Ozponds]

It’s pretty normal for some water to come out the breather hole, hence why I often add a valve or an elbow and some vertical pipe. Don’t overthink the sedimentation, monitor the pond, if the pond is going fine don’t worry about the biological processes inside the filter they are humming along. If you drain the filter you won’t be losing too much bacteria as they are clinging to the surfaces, as long as they don’t dry out many will remain inside the filter.

[@Wakeupandsniffthecoffee]

Having done aquaponics with fish and biological filtration that in turn feed the water back to my grow beds as nutrients for the plants and then periodically it is drained back to the fish, I'm a firm believer in this. I have a large catfish my granddaughter caught about 3 years ago and I've had it in a tank over winter, when the top froze over to summer when algae and extra warm water compete for oxygen. I finally brought it into the house. One reason it works is I never totally do a full cleaning. The filter stays mucked up until I rinse the excess off or maybe change the charcoal filter. This all keeps the tank very clear. My next challenge is a duck pond I dug. We have clay soil, so it holds water pretty well, but I need to either make a plastic barrel bio filter and maybe even a small bog to clean it. I'm hoping with both ducks and geese swimming in it and doing their business that I can actually clean it and get rid of the summertime algae bloom.

I have no first hand experience in this. My assumption is that it’s perfectly fine as the biological activity in the pond over winter is also dormant. In spring start it all up again and off you go.

[@eloisecamire3741]

If you search for “how to winterize a pond” you will get great explanation. From what I found most northern ponds will get a clean in spring to manually remove string algea, they are active when the bacterias are not yet, and then as soon as the water temperature rises to around 10c the beneficial bacterias will be active again.

Idea was to implement air output at the bottom of the bog(those perforated hoses to watter your garden), and let the watter move up with only help of air, but conccern is if the watter will be moving fast/slow enough, and if the direct output of air in bog does not kill the bacteria.

[@Ozponds]

Air won’t kill the bacteria.

[@Sahy89]

@@Ozponds Thanks, so to now use small barrels to build test, if air draft through rocks will be enough to pull in watter and move it up.

[@Ozponds]

@@Sahy89 I’d love to hear your results 👍

[@lornapenn-chester6867]

Questions!!!!… does this system work outside of a tropical environment? Like the U.K. or ireland? And does it clean the water well enough that a pond could be for swimming as well?

[@Ozponds]

Yes and yes.

For locations with winter freeze up. Is the barrel filter run year round? I have an air pump that keeps an open space that vents the pond. My pond has a natural bottom. Previous to installing the air pump, I had a massive fish die off one winter when the pond was frozen over for weeks.

[@Ozponds]

If it would freeze solid it obviously cannot run all year. If you experience such temperatures there’s no need to worry, I recently made a video on the bacteria during cold winters 👍

[@dont.ripfuller6587]

How effective would fresh water mussels be for this?

[@Ozponds]

They are a good addition. If you want clear water I wouldn’t be relying on them alone.

What does ongoing maintenance on a bog filter look like to remove the excess fish & organic waste?

[@Ozponds]

I’m about to flush my bog in a stream for the first time, it’s at least 2 years old. If you scroll through previous videos you’ll find the maintenance process on my different bog filters. Hope it helps 👍

[@brycedaw7105]

I'm just wondering if you have a video of the filter part in the water so it don't suck up the little fish?

[@Ozponds]

I’ve done a few vids on how to position the pumps it depends on the size of the pond how that’s configured. If it’s a small pond there’s a video titled something like how to protect your fish fry. It’s one of the early videos I uploaded to KZbin. If it’s large look at my diy skimmers or intake bays 👍

[@FinancialPrepper]

Great video. I'm building a pool inside my three acre pond. Sounds crazy but we enjoy swimming in the pond. We don't enjoy the perch eating us alive. The brim here in Louisiana are vicious. I was going to set up a filter a lot like what you do to filter the water going into the pool, from pond 3 the filter into the pool creating a positive pressure of clean water that will displace the dirty water trying to leach in from outside . my worry is it's going to grow algae inside the pool. Would ultraviolet light filter help. And the ideas?

[@Ozponds]

UV will kill suspended algae. It won’t kill all types of algae.

Hi, Kev, I just found this video, and then started galloping through several of your other videos, and your website - everything looks so fantastic, you are providing such an AMAZING amount of info for *everybody* !!! I laughed at a different video with the bucket of fish, and the water clarity be maintained primarily by K9 powered water changes LOL ! I have come back to *this* video (even though it's 3 years old), with a question about something you said in *this* video, and I was searching all your other videos and your website trying to find out more about it. I even tried searching Google for various combinations of keywords, and could not find anything relevant. In your video, above, you mentioned that if you don't have an electrical power source to power the water pump, near where your water feature is going to be, that you can use "an air line" to pump the water ... But that's all you said about it. Have you already explained more about this somewhere else? I have been looking *all over* your videos, for some reference to how a line filled with air, could be used to pump water, in some kind of recirculating-stream/waterfall creation, and all I can find is references to basically artificially oxygenating water for fish - pumping air into the water, at the far end of the tube, and that's it. I did find an "AI" summary, that basically said an air line could be used to siphon water downwards, or could possibly be used to "lift" water upwards using compressed air and suction (it didn't explain how), but it went on to say that this was typically used just to introduce oxygen into the water element, not to actually *pump and move* the water. If you have already explained this somewhere at length, can you please tell me where? And if an "air line" can really be sized up to handle a recirculating stream and waterfall, how to you set it up, and calculate the sizes of ... whatever parts and equipment are required ? Thanks much! I hope you see this comment/question, partly because I hope you might answer it, but mostly to say how grateful and amazed I am at ALL the FANTASTIC information and detail you provide, and how clearly you explain things, and how easy you make it all, to understand !!! Many, many thanks !!! -Lauren

[@Ozponds]

I use an airstone on my dream pond. The aerator is 30m from the pond. The air is pumped into the pond via a garden hose. In terms of creating an actual circulation pump using air that’s a bit more complex to construct and not something I’ve built. “Bubble pumps” are pretty straight forward, that’s your keyword to search. “Airlift pumps” should deliver more flow, another keyword. Good luck 👍

[@tenguokoku]

​@@Ozponds Thank you so amazingly much for replying !!! I really appreciate it ! And so fast ! Thanks for telling me the better keywords to search for - I've never heard of them, so I never would have found anything relevant. 😊 You are so terrific ! I subscribed yesterday and wandered in all directions through your KZbin videos, she was in awe of the careful lesson plans laid out in your website. It's going to be a couple years before I can start building water elements, but I took lots of notes, and will be coming back to everything you've so wonderfully explained, then ! Many thanks !

[@Ozponds]

@@tenguokoku I’m happy you’ve found my content useful. I want your water feature to be a success 😊👍

[@tenguokoku]

​@@Ozponds You're awesome ! Thank you ! One of the reasons I laughed out loud at your other video where you explain that your method for keeping the water clear in your tiny little fish bucket water element, was because your dog was drinking from the bucket and helping with the entire water exchange process... I had just come from a lecture and workshop on making your own water element, on Saturday morning, and while the lecturer and workshop staff were focusing on recirculating *waterfalls*, the lecturer tossed off a comment about how you could use a liner to make a recirculating *stream*... Literally just one sentence about that long, adding that a shallow stream requires less digging than a kit with a waterfall element in the middle of it, where the support base with all the equipment has to be dug out and hidden on like a foot or more below ground level (although he went on to mention that you could avoid digging altogether, by putting the entire kit base and waterfall element on top of the ground and just surround the unsightly parts with flowers and plants, or even put it up on a table, with whatever decorative plants, or bricks, or whatever you wanted, to hide the plastic waterfall kit base) ... Anyway, a miniature babbling brook is something I have wanted to create - with a waterfall - even if it's all tiny - for many, many years. Later, I was enthusiastically talking about the lecture and workshop with a friend, and he mentioned that he and his wife have a tall fountain in their winter home location in Arizona - they got it free, from a professional landscaper friend, who gave it to them because his client was just throwing it out - and that landsdaper mentioned that you need to constantly *change* the water out, not just add more to compensate for evaporation, because otherwise the unevaporated salt which remains, results in mineralization crusting everything over. I have sheep, and goats, and flock guardian dogs, and therefore I already have automatically filling water troughs with float valves in them, which automatically let more water in, up to the desired level, when the water level drops low enough to make the float bob drop down, and open up the water line, until the water level rises back up high enough to lift the float bob back up into place, to block any more water from coming in. I have *never* seen any mineralization in my troughs, and the water here is very hard. Right now, I guesstimate everybody is drinking about 25-35 gallons a day. So, that's about 1/3 of the main 75 gallon trough I think they mostly use, although there are two others that size. But I figured that's a pretty high percentage of water exchange *daily*. The water is always crystal clear. Mulling that over, and being lazy, I wondered, if I built my "stream" correctly, and of sufficient size, so that my sheep/goats/dogs could all drink from the "stream", and if I added a regular stock tank float valve to the end of the waterline feeding the stream, wouldn't that solve the entire water exchange process concern for the recirculating stream and waterfall? I mean, it would, in essence, be the same water supply situation I have already, only a lot prettier, more aesthetic, and more fun. So, I was feeling pretty proud of how clever I was, to imagine solving the water exchange maintenance and mineral buildup problem, that way, and also creating a low maintenance water feature, and also having my cake and eating it too, with having a very enjoyable recirculating stream with a waterfall... Combining all that with simultaneously providing water for the stock... I wasn't sure the idea would work, but it *seemed* like it should. I was feeling pretty clever... Also, the *recirculating* water probably wouldn't *freeze* like the water troughs sometimes do in the winters here... So... another problem solved. Then I came across your video where you, with the help of your dog, were doing exactly the same thing, in miniature, basically in a *bucket*, and I laughed out loud with delight. It confirmed my idea would work? ...Doing water exchanges, thanks to your dog! It still makes me laugh. Anyway, thanks again ! It's going to be a couple of years before I can move and start in on all this, but, I intend to come back and really dive into all your tutorial content *then*, for sure ! 😃 Thanks again ! -Lauren

@@tenguokoku I think you’ll create something really special.

Can a venturi pump that pump air to water be a working alternative to bog filter?

[@Ozponds]

Oxygen is always helpful but it isn’t a filter.

[@llbailey9946]

dumb question.. what do the bacteria turn the nitrogen into when they process it? I understand the algae and plants use it to grow more and bigger, but what do the bacteria do with it?

[@Ozponds]

Same thing. Consume energy, grow, reproduce.

Look up "the nitrogen cycle" 5 minute cartoon by Jim Sol. It does a fair job of explaining a complex subject pretty simply.

Great video, one question: -How will the bacteria in the mid to bottom get sunlight? -Isn't it better just to fill in the base of the pond with pebbles for the bacteria to grow there?

[@Ozponds]

That’s two questions 😉. I believe these bacteria don’t require sunlight.

[@rodrigo_paiva]

@@Ozponds that makes soo much sense, thanks. What about just covering the bottom with pebbles for the bacteria to attach? Or will it be overrun by the algae anyway?

[@Ozponds]

@@rodrigo_paiva there’s lots of ways to filter water. It’s about matching the amount of surface area for bacteria with the amount of nutrients the pond needs processed. Therefore are you confident that the pebbles alone will provide enough surface area? Or do you need more? I choose bog filters because I know how to size them for my desired results.

[@JamesfromBreezy]

Hey Kev. I'm collecting rainwater in whiskey barrels and am looking for a way to constantly filter the water. The main purpose for this water is for use on the Garden when it's dry. Do you think a bog filter would work inside of the barrel?

[@Ozponds]

A bog is my favorite method of filtering water, but I think in your situation all you need to do is put a cover on the barrels, that’ll stop mozzies and algae taking over your water.
