help - foamy water

[Daikyo]

This year as my pond comes back to life I am bothered by the amount of foam building on the surface of the pond. I have a small cascade, fed by a large pump running through a green genie 24000 filter. As the weather warms the foam begins to build - any suggestions

Foam is caused by dissolved organic compounds (DOC's) in the water. The foam will eventually dissipate, but you can help it along by first making sure you don't have a lot of decomposing plant or animal mater in your pond. Then run your water through some activated carbon for a couple weeks.
