I know this question has been asked before, but I can't find an answer that helps my situation so please bear with me.
Our pool has been open for about 2.5 weeks. We followed the same opening procedure as previous years, including the same chemicals, same brands, same dosage, etc. This year we are getting a thick white foam on top of our pool when the pump runs. Once the pump is turned off, it seems to disappear, only to return the next time we run the pump and get worse the longer the pump runs. We have tried skimming it off the top, filtering it out, etc, but it keeps coming back. I understand that algaecide is the normal culrpit, but we are using the same non-foaming brand and same amount as always, and none has been added to the pool in over 2 weeks.
I have read that there may be an air leak, but the foam does not gather near the return jets and seems very thick to be caused by air. The water chemistry seems normal, I am at a loss for what could be wrong. The pool itself is clean, but no one is going to want to use a tub of foam. Thanks for any advice anyone may have.
