I think what I scooped up was actually Koi semen. 30 minutes after I put it in the container, it was dissolved. It looked like foam when I first scooped i tup. Exactly right! Spawning is one of the primary causes of foam in a garden pond. It _is_ a good idea to scoop out the foam. Because my ponds are netted that would be a real pain in the keester. It disappears in 24 hours on it's own. The first time they spawned several years ago I checked for an ammonia spike - there was none. It's not a hard rule - and the bigger your pond the less likely it is to cause trouble. If ammonia never appeared, it's not a problem at all. But foam of any kind indicates a high organic load in the pond, and scooping it as it develops is the simplest form of control. If it was a real problem, then you'd want to consider a protein skimmer - which wouldn't be a problem with a netted pond. -- derek Hmmm. I have a reef tank, and everything I've ever read about protein skimmers (I have two different ones) says that they don't work with fresh water. I haven't actually attempted to use one this way so I am just going by what I have read. Something about the surface tension being to low in freshwater. Now, if the water was really fouled up, it might work for a while. |
