I had to fire these guys today... For a few months (since they started), my pool water has been great. A week or so ago, the wind picked up and blew some leaves in my pool. The poolsweep took care of the leaves, but the water started to cloud/green a bit. I called and they said that it was probably the pool pump. He took the pump apart and told me it looked fine. He put some clarifier in it and said it would be okay. I called back to say that it wasn't. He said that he again suspected the filter cartridge. For months it was fine, but now, that the water isn't great, it must be the filter... No accountability.
