i'm finding that my 200 skims better dirty. about 2-3 days after cleaning the cup, it really hits its stride. about 7-10 days and it's not pulling as much and needs cleaning again.
i took the fitting off my venturi while the pump was running to look for buildup, there was some there but nothing close to obstructing the air intake. how many folks are running ozone into theirs? it seems like a lot of you are. is it possible that's contributing to the buildup of the deposits in the venturi?
no one's really said it, but i think this is a significant design flaw. the fitting on the venturi is the part that requires about 80' of teflon tape to fit properly. removing that monthly to check for blockage is a PITA, there's a lot of tape to clean off the threading before retaping and reinstalling the fitting.
breadman, you have way too much energy dude. send some my way.
