I'm having problems getting my pool to clear up from the green blue tinge and have been following instructions in 'Pool School'. Its been two weeks now with my pump on 24/7. The pressure gauge does not change. It stays constantly at 25 PSI even after backwashing. I have a bunch of dirt in the pool that I tried to vaccuum but it comes back into the pool as a brown water.
-any ideas on the pressure gauge staying the same? I replaced the sand July 2008.
