I recently followed the advice I read here and got rid of a swamp...it is now cloudy, and it had/has lots of gritty white stuff on the walls of the pool. This had been there all along and is falling off some since the chemicals got more under control.
These are my numbers:
I backwash the sand filter daily and vacuum regularly.
Vinyl liner, 25,000 gallons in upstate ny
what else should I do?
