    if money is a option mostly due to lockdown you could make one for sheets of 18mm plywood , seal it with PU18 and paint each tier with G4 POND paint or similar. all in could only cost £100 for something of a reasonable size

    im making one once ive finished making my indoor 2300litre koi vat

    thanks mate, was my first attempt I had thought about doing these as a business but sadly no-one's interested shame really cause I could save folk upto a few £1000 and I would of really turned these into professional looking filters, or all in one units.
    it works on a timer (adjustable) and float switch had teething problems for first few months altered a few things and its ran faultlessly for last 6 months or so. 9 months since installed. very basic with 2 x 4" inlets 2x 4 " outlets 50 micron screen upto 30,000 litres but runs best on around 25,000 litres. size is approx. 700mm L x 500mm W x 600mm H

    All items used are off the shelf so easy to source .

    I don't think the material a shower is made of is a big factor at all tbh (and I have a genuine Bakki).
    How well your shower works in the real world will be a factor of:

    1. Air flow (you don't want a design that doesn't have a good air flow between the trays)

    2. Flow rate (make sure you allow for a higher rate than you initially think you will need, just in case, who knows what the future may hold?)

    2. Media (lots of stuff written about media, but best to avoid media that 'dissolve' over time causing irritation to fish gills etc., pick something that you know has v good porosity and longevity. for many of us BHM fits this bill but ofc there are many copies making various claims on the market. decide if your investment is worth the risk for the savings offered)

    Lol I forgot that was on there. I was using it to place my winter covers on allowing the water still to return from the shower

    I’m off to remove it now

    I am correct in thinking that air circulating around a Bakki shower is important , or was that just a claim to promote the Momataro Bakki units ?

    I think air is important to aid gassing off of ammonia etc also helps get oxygen into the water.

    There was some discussion about this topic in Chip's interview with Raad:

    https://www.koiforum.uk/water-treatm...tml#post317376

    and regular forum members will be familiar with me occasionally mentioning this aquaculture video, which happens to show deliberate Co2 stripping/degassing:

    Kaldnes® RAS, Recirculating Aquaculture System - YouTube

    it's not unreasonable to suggest that smashing water against ceramic, thus temporarily increasing its surface area (by forming a thin film) and thereby increasing its exposure to environmental air, may well increase gaseous exchange (nitrogen, Co2, etc.).

    I'm very far from being an expert on the topic of gaseous exchange (I lack a doctorate in biochemistry, biology or aquaculture), but I think I remember reading, years ago, that some koi hobbyists claimed that they suspect that using bakki showers may have reduced the levels of carbonate in their pond system. If true, that's quite interesting, because if a bakki shower was perhaps increasing off-gassing of Co2, which I believe to be plausible, then I suppose that loss of carbonic acid might well lead to a reduction in available carbonate within the pond system, since (so far as I understand it) carbonic acid helps keep carbonate in solution.

    Feel free to mock me and throw insults if I'm totally misunderstanding this! (especially Syd?)
