      Foam caused by not digesting proteins?

      I was watching a KoiPartner video, and he said foam is caused by your koi not being able to digest the proteins you feed. He said too much feeding can cause it too. Are these the only 2 ways foam can develop in your pond? Will any water conditioning additives cause foam also??

      Recently I was feeding a small amount of hikari wheat germ about 2 or 3 times a week when the water temperature was about 50 to 52 F. My pond developed a noticeable amount of foam with a small amount of yellowish foam mixed in…

      Oils added directly after processing or present in feed ingredients will leach into the water and contribute to foam. Foam amount varies by food types and brands. Power feeding always generates more.

      Dissolved Organic Matter DOC vs calling it protein is a better term since it's a mix. Since feed is less than 40% protein there can be many undigested ingredients.

      Agree with Batman.

      Wheat germ feeds can increase DOC, not because of a failure to digest, but because at the same time as wheat germ supplies highly digestible proteins, it also supplies a high level of dietary fiber. This can result in more of the organics dissolving in the water rather than being bound in solid waste. DOC is from having living creatures in water. ....Consider a foam fractionator if you have excess DOC, particularly if in an area where water changes have to be limited.

      If koi clay does not dissolve in water, how does it help reduce foam?

      Is string algi not a by- product of overfeeding and nitrate

      Brought about by insufficient water changes.

      If clay reduces foam (which I do not know from personal experience), it would be by adsorption, as with adsorption of ammonia ions. ....Despite all the parroted statements, nitrate is almost irrelevant as a nutrient for string algae. As long as there are living fish releasing ammonia, the ammonia will be used before the nitrate is touched.

      I am not quite sure if clay (and particularly Montmorillonite) actually has all the miraculous properties that are advertised, but it is used as a flocculant even in water treatment plants. Practically clay particles, particularly at higher pH, have a negative charge and tend to stick to and bridge between the other particles in suspension making them precipitate in larger "lumps" making it easier to remove them

      I am under the impression it is used to reduce leakage in the mud dams.

      Or you could get a few hundred truckfulls of clay and build yourself a 5 acre pond...
