    I really would like to know what the most important function or functions of these towers are. Break down fish feces, supply O, filter the water, move water and so on. The reason I ask is for human septic systems, anaerobic bacteria is the machine. O will kill this bacteria so tank must be sealed to work properly.

    I don't have any experience with the strength of acrylic welding to complare with PVC, but have priced clear and colored acrylic and it seems comparable here to PVC. Someone with experience building sumps for saltwater may have a better perpective on acrylic weld strength than I.

    A bit of a misnomer there Gary.
    While it is true that "some" wastewater treatment systems rely on anaerobic digestion, many are aerobic systems instead. It is all a matter of form. The anaerobic systems are "nitrifers" that tend to produce large quantities of methane and noxious (sour) gases as a byproduct while the aerobic systems are virtually odorless and heavily aerated.
    Some utilize both at different stages of the process, but they must be carefully managed to prevent the gases from reaching an "explosive mixture" in process. That can get ugly.

    I believe you mean "de-nitrifiers".....

    You had a pretty good game plan when you came to me, so I don't deserve much credit. I just saw a few places that could use some improvement and offered suggestions.

    It looks like you picked up plastic welding pretty quick. The whole unit looks very nice, and well constructed. It will be interesting to see if you experience any water quality changes when you add the air blower.

He lives in the Jacksonville area and has developed some inventive products for use with ponds. His low-head shower filter has gotten interest from those who have seen it. He has more on the way. He recently partnered up with some folks with a bit of capital, so a true product line with distribution just may be around the corner. Those coming to the Central Florida Koi Show can check it out. He has a booth in the show tent vendor area as Deepwater Koi Innovations. A few years ago, CFKS was the venue selected by a Taiwan company to introduce its filters to the U.S. market. You now see their Litek ads in KoiUSA and they are building a distributor network around the country. I am hoping Zac will have as much success and that CFKS can be his kick-off.
    Thanks for the brief introduction Mike. I assume this is Michael Mcmahon? I am very excited to reveal some of my new designs at the CFKS and hope to meet and make a lot of new koi friends. We will have a variety of filters to suit different pond applications on display, so be sure to stop by and say hello.

    Zac

    ???

    Most important to me is bio-filtration.

    Secondary is oxygenating the water.

    A pump impeller is good for moving water and breaking down fish feces.

    KK, you may be a tad confused concerning the bolded section. There are both anaerobic and aerobic septic systems. The thing is that aerobic septic systems are 20 to 30 times more efficient in consuming waste. Run a search to verify. Here is but one of many links:
