Took out 2 gallons of brown garbage the first day. Took about 1-1.5 gallons each day for the next 2 days. My water has never been more clear!!! Not a drop of foam on the surface of the water. Really happy with this project...Highly recommended!!!

    A picture is worth a 1000 words, but I do not have a picture of the DIY I use.

    The bubbles come from from a swimming pool jet.

    I have attached a picture of the original idea that was published in Koi USA.

    I have made a couple modifications.

    When the weather gets better, I will try and remember to take a picture.

    Hey Richard,

    Based on that little diagram, it seems like the foam would have to travel a considerable vetical distance before being able to get dumped out of the aeration column. I would think that a taller aeration column -- with the water exiting near the top and the foam outlet just a little bit higher than the "turn" the water takes to flow onward -- would be more efficient?

    What the heck are dietary protein comments doing in this thread?

    I get the feeling that someone googled up "protein" and started posting up questions anywhere they got a hit without regard to relevance of the topic at hand...

    I think it's a spammer. There seem to be quite a few at the moment that post almost relevant messages for some reason before spamming properly.

    Re: previous diagram
    The water enters from the Right through a venturi jet (L). I use a 1.5 -> 3 offset adapter (K) used in R.V.s. to help the incoming "jet" of bubbles to rotate. The diagram is poor and not to scale. The pipe (P) is not glued and therefore is the adjustment for foam.

    See attached new (unfinished) drawing for a better idea how I do it.
    I will go out now and take pictures.

    OK, attached is some real pictures.

    The first picture is a "3 inch" model I took off of a 1200 gallon pond.
    The pvc venturi tee jet is missing and the the upper 1 inch pvc pipe and cup is missing. Note the offset 1.5" -> 3" reducer.

    The second picture is a "4 inch" model that is installed on my 2500 gallon pond. Note the dried foam on the pipes.

    My experience with "protein skimmers" on fresh water ponds is that they do not always produce foam. During the summer months when the amount of food being fed and the amount of fish waste is at the highest, I get a fair amount of foam.

    The "protein skimmers" pictured are for DIY ponders that like to experiment with filtration.

    The way it was explained to me was the initial foam produced is not concentrated enough to maintain bubbles to "climb" the dry column.
    As more and more foam is added to the area just above water in the larger aeration column, a longer lasting, more concentrated foam is produced that climbs the dry column.
    You adjust the foam by lengthening or shortening the top I inch section of pipe.
    If the foam is too runny, you will loose more water and the protein skimmer will act like an aquarium under gravel filter air-lift pump.
    If the foam is too dry, it will not climb and collect in the "cup" at the top.
