    So does this design make any sense? Gravity fed to some kind of sump...not sure what to put in there, then pump raised water up to sieve about 1.5M, then water heads through 3 barrels, Moric filter, then 2 barrels of K1, one static one moving bed and then gravity returns back to raised bog, witch a water levels approximately 75cm above ground level. The barrels are raised a little bit to allow for a waste pipe at the very bottom of each barrel. Would this work or is it just madness?

    Any feedback would be greatly appreciated. :) koifilterredux.jpg koipond3.jpg

    will it work maybe will it leak maybe .Will it freeze maybe .The leaks are likely where the tank adapters enter each barrel and will always have to be checked .Are you protecting it from freeze in a building and are you prepared for the power bill for that sized pump I am no expert in pond filters so look at this as I have no clue ,but things you might have to think about

    A Jebao 10k LPH eco pump runs at 75w. I probably spend more on chewing gum in a year than I will on that thing lol. It's not going to freeze, we're in zone 8 and it barely gets down to freezing here. Tanks will be connected using either uniseals or bulkheads with silicone sealant, so hopefully no leaks. The real question is, will it work mechanically. Is this an efficient setup? What the heck should go in the 'sump'? Brushes? Also the return feed starts at 1M in height and heads down to about 50cm off the ground into a manifold that feeds a raised bog with a water level of around 75cm, so the water should flow fine from filter to bog right?

    Welcome :)

    I'm not a filtration expert, but this design seems complex. Are you planning on the sump being a settlement chamber? I'm wondering if you need both that and a sieve, as both remove solids. Could your bog serve as biological filtration? Are you planning on keeping koi?

    It's kinda complex lol. Honestly I'm just throwing lots of things in there slowly cutting out what doesn't need to be in there. This pond isn't very big, only 2000 gallons and will have max 8-10 koi. I think initially I will just make that sump box a brush box to take out big stuff and the Moric filter and static beds will take care of fines. Moric filter and brushes take very little time to clean out, maybe the static a bit longer, but that will be less frequent, hopefully. Since the koi are all going in pretty small 6-7", hopefully, this system can handle them for a year or so before I need to get serious about putting in a proper sieve.

    Feedback is very helpful though, no matter how critical. If people say it's trash and won't work I'm more than happy to scrap the whole thing and start over haha.

    So this is a more practical design.

    Hello and welcome! That’s a fancy set up! What is a “moric” filter?

    You’re going to have a bog and all the other filtration methods? If your water goes through those other filters before it returns via the bog, you will have removed the nutrients that the bog needs to flourish. IOW, you will have defeated the purpose of having a bog, it seems. Most pond filtration systems are one or the other: a bog or a DKP (dedicated koi pond) set up, or a DKP with some water pumped directly to the bog, bypassing the other stuff. What kind of fish will you have?

    The pond will have koi, around 8. Also the bog plants need nitrates, this setup has aerobic bacteria media so they will remove ammonia and nitrite but do little to remove nitrates, which the bog plants will help to keep down, to a degree. At least this is the theory. Also the bog isn't your classic bog filter, it's more or less a relatively thin layer of gravel, only deep enough for some iris and a few other plants to grow. The gravel sits atop an egg crate or similar mesh (thicker gravel first to prevent smaller gravel falling through the grate) to keep it raised and beneath the gravel shelf is an empty area of water with a drain. I designed it that way to be easily cleaned and prevent anaerobic muck build up, as happens in thick gravel bed bogs. Again, this is all theory.

    Also thanks for the welcome :) and a Moric filter is a type of filter sock filter designed by a guy called Ronni Moric, in Denmark I believe. It's basically a more easily cleaned version of a typical filter sock setup.

    He showcases it here

    To supply water to a bog usually the only thing to have is a leaf catch before the pump to protect it from large solids.
    With filtration before the bog I think you will starve it of nutrition.. You could split a line after the pump and send part to the bog and part through the filter system.

    That's a great read, I'll check it out now, thanks. Yeh, I guess I could send part of the flow back to the bog after the pump. I could do something crazy and have that line run to the manifold and have the line running from the filters go straight back into the pond via a directional pond return. Maybe have it push the current toward the skimmer, or a least give the koi a little area to swim against. Maybe good exercise for them?

    I build both types of the standard bogs are concerned one is a foot and a half of pea stone. with the water pumped to the bottom of such through perforated 2 inch pipe.
    the second bog has the aquablocks and snorkel and centipede with a 6 foot deep bog starting with small volleyball sized rock around the snorkel. then a layer of aquablocks. and1 foot of 1-2 inch stone over the aquablocks with another foot of 3/4 and pea stone. All I can say is there is only a basket strainer on the pump, and if I cloud up the pond where I can't see any fish what so ever. Without fail come morning the pond is crystal clear.

    I know this isn’t answering your question but since you are in the planning stage you might reconsider the size of your pond if are hard fast on keeping 8 to 10 koi in1850 gallons (7000L) pond of water. I think that is the pond size you mentioned in another post. The bioload will could overwhelm the system as they mature and reproduce.

    I might end up feeding the skimmer directly to the bog via pump, haven't decided yet. I have a small spare pump, but it's only 3k LPH. Not sure if that matters with the 10 or 12k LPH that will be going through the filter.

    Stephen, the diagram I was working on listed 8700 Litres, although we're upping the size of the pond now to 8X12 feet, closer to 12000 liters or around 2600 gallons. That doesn't include the volume of water inside the bog, which may add another 1500 liters. Still not huge, but hopefully it can take 10 Koi.

    Beautiful! My bad. I was mistaken from one of your other posts. Sounds like a fun project.

    I am a firm believer in over sizing filtration. slow down your filter water speed from your dyi filters and I am sure they will work at the optimum. they are designed to remove organics. And on the bog have a second pump pushing slowly unfiltered water. I would be willing to bet between the natural boi filter the bog and a mechanical filter all would be good
