I just watched a video where a guy claims these pools cost around $5k a year in bacteria after each season. I like your approach much, much better. There's any number of videos where they say they are virtually free to run...and this seems to be much more logical to me. I used to run a 300gal planted fish tank. The bio load and water volume were well matched, and I used a LOT of plants, and plenty of scavengers (pleco's, crawfish, shrimp, etc). But I found the real secret was simply over filtration, and a LOT of flow. I often wonder how that will work when I transition my experience to a natural pool/pond.

From my personal experience: Down-flow (input from top, output at bottom): output has to exactly match input. - If output - If output > input, bog filter will be empty. Once the filters start to clog, output (top to bottom) will decrease and unless managed (i.e. clean filter or reduce input), the bog filter will start to overflow. Up-flow (input from bottom, output at top): easier to manage as output cannot exceed input. - If output - If output > input, bog stays full and output flow matches input Once the filter starts to clog, the flow to output (bottom to top) will decrease, causing input to decrease. Bog filter will not overflow.

Bottom flow going up seems to be the least complicated to build, and maintenance. I clean mine once every five to six years, only because once the vegetation has established itself, it becomes a serious workhorse for filtering. The entire filter is about 2' to 2-1/2' deep (60cm to 76cm) 2" (5cm) slotted pipes are fashioned along the bottom into a shape that runs the contour of the pond with one intake, and about a foot (30.48cm) of 3" (7.62cm) gravel is filled over the top of the piping leaving about a foot of water for plants to populate the gravel. This bog makes it convenient for dechlorinating municipal water when added to the pond though aeration, and addition of dechlorinator, and in my hardiness zone the plants are the first up to start filtering when the bacteria is still in suspended animation from extreme cold winter temperatures.

I have a 20 foot by 15 foot pond that is about 5 feet deep and crystal clear water, I mean when I drop my gopro in it doesn't look like there is water at all, just a load of flying koi, this is completely down to a bog filter. I took inspiration from oz ponds! I do though, harvest rainwater and drop in 3-400 gallons in every week or two. I have calculated the cost of the bog filter including plants to around £1200. If I were to use an off the shelf filter with UV etc I would have been looking at £2500minimum. Plus I get massive satisfaction at creating my own little ecosystem. Thanks Oz ponds!!!!

Cheers dude 😀 The only additional point I would make is that I think the top-down filters are far bigger because they use a lot less pressure, which I assume means they need a greater volume of slower-moving water to pull from. The choice seems to be clear... if you don't care about streams and waterfalls, and want the cheapest to run swim pond, then go for top-down filtration with bubble tubes. If you want a stream or waterfall then you have to have a decent pump, which means you can save some space and go for a bottom-up filter, which can be crafted to add to the look of the whole design. My next question is concerning how the water moves, as you showed with the glass and the tap (I'm convinced the power of the flow would send all the new water swirling to the bottom - you could have added some cordial and made squash to show how the water moved). Anyway... without some sort of deep level powerhead, wouldn't the water come down a stream, hit the pond at a slightly higher temperature, go straight across the top and into the bog filter, and back round again? You'd just end up filtering the top few inches of water over and over, whilst the slightly colder main volume of water in the deep area never moves? I've seen ponds with additional jets and they make sense, but I've also seen some Aquascape creations that don't seem to have anything but the wetland and stream.

I’m making a small swim pond for the back garden and have a 2m high wall that curves around the pond. To save space and not have to have a sizeable regeneration/ planted zone; I figured I could make a hollow faux rock wall in front of this and sit a wheelie bin in it as a top down bog filter (I don’t know if a pond pump would be able to shift water through a bottom up filter to say 1m head height?). Maybe have two of these either side of a separate waterfall going into the pond on a separate pump so that could be turned on and off as needed to save energy. I thought about using airlift pumps but it seems like a nightmare trying to get any significant head height off those things. Any suggestions?

That is true. Down-flow can be easily powered by an air pump, however I don’t think the energy saving argument stacks up anymore. In recent years pumps have gotten so energy efficient. If you select the right pump they can move just as much water, in some case more than an efficient air pump. But if swimming air pump has massive advantages as no electricity in or around the pond.

I have a space to remove wastes from the bottom of the bog but so far it looks very clean (no solids). The battle with hair algae is still ongoing, I think I can remove it faster than it grows apart from the fact that it is chock full of tadpoles so I need to be very careful and only pull out small pieces at a time so I can check and return any inhabitants to the water.

Have you considered that in a down-flow filter, when using principles used in trickle filters, the water that flows down will be highly oxygenated as the water has splashed down to the surface of the filter's water level? In an up-flow filter, the water your pumping down under the filter will have come from the bottom of your pond, which arguably is the least oxygenated body of water in your pond. I might argue that highly oxygenated water in a down-flow setup might promote more active bacteria activity.

You’ve obviously not seen how I set up my ponds with a skimmer/ intake bay. Water is pulled from the surface. A trickle down filter is very different from downflow bog filter, usually the filter is fully submerged. Trickle filters are extremely effective at converting ammonia to nitrite, then nitrate. They are not submerged. But they won’t remove the nitrate. Both bog systems have a greater potential to process the nitrate. But of course it depends how it’s all set up. Like I mentioned in the video there’s heaps of different ways to have a successful filter system, I just outlined why I do it the way I do it.

@@Ozponds yer it dose sound funny. Though it changes what and how much filtering you need I have found. As I plant heavily and filter well also finding some plants need feeding ever though I’m feed the koi like mad.

There’s a funny relationship with man made phosphate and natural phosphate, or phosphorus I always get bamboozled. We all need to be aware what we add to the system stays in the system. Same on a global level.

@@Ozponds well I’m not sure checked the back of the plant balls I put in said it’s 100% blue loam? They had been in the shed for years! Seems ok fish and plants happy now. My thought was where these plant have been put maybe highly filtered water with not much natural mechanical waste getting to them. Maybe a bog that dosent filter as perfectly could be helping a different set up?

I made a downflow because I didn't want my pump to overheat when it needs to push water through the media

There ya go. I didn’t even know that was a thing. I’ve never had a pump overheat.

If the Down-flow is working stick with it 👍

I'm not sure because I rarely turn it on as my pump is meant to work at less than 3 hours at a time and needs to rest the same amount of time@@Ozponds

Down flow could be easier to build into the floor of a pond I suppose.

For sure. Under-gravel filters and suction grids both pull water down through the media on the bottom.

"Often PONDered myself"

Your intuition is incorrect. Water flowing from a tap with a gap does mix with the rest of the water in the container in a turbulent manner. Pretty basic fluid dynamics. You can try this yourself with a little food coloring and just use a pitcher or whatever instead of the tap. Science is fun. It's visually similar to blowing smoke. Username checking out today!
