Put Rover jr. in to do some cleaning ("shocking process is now over, cholrine coming down and Water boatman back in the pool ) Attached is a picture of the "white chunks" that it is picking up. This has happened one other time last week. What is this stuff?
I added DE to the filter, but DE is much finer than this isn't it? It almost has a texture of brittle plastic with a bluish tint. Could the liner scale off?? My numbers are actually better than ever right now.
