Pool was opened 4 days ago with a lovely green color due to a break in our pool cover. The algae has since died (FC has been holding at 16 w/CYA at 40ppm for a few days) but b/c I noticed very large particles suspended in the pool water in the pool water after 4 straight days of 24/7 filtering thru our 14" Doughboy Powerline sand filter filled w/zeosand, I put a debris sock on the skimmer to help it along. After only 30 minutes, the skimmer sock was literally filled (I lost prime) with what appears-to-be sand filter scum, but with absolutely no sand. The particles in the sock are a very soft coagulation of synthetic and natural fibers(seems like cotton), hairs, very very minute blue flecks, and a whole heckuvalotuv other small organic **** w/the same grayish green color as the sand. I also found it very odd that the pressure never went higher than 3psi over the original pressure of 15psi even tho a ton of debris was accidentally put into the water from the cover break. We took the sand out of the filter to see if anything inside was in disrepair but I immediately noticed how clean the sand looked.
The zeosand was changed the beginning of last season after switching to chlorine from baquacil. The water was clear last summer for the most part (except when battling cloudy water during the extreme heat). The pump and filter are only 2 years old (as is the pool-- 7900 gal 12x24). I've suspected for some time the the 1.5HP doughboy that the pool installer (has since gone out of business...go figure) supplied with the pool is much too large but I can't find any info if that size pump w/a 14" sand filter would cause any similar problems. Our Doughboy pump does not have any laterals to break (it's got an underdrain).
Does anyone have any idea what would cause the filter scum to go into the pool? Should I be looking into a buying either a larger filter or a smaller pump? Is the pump too large for our filter and what problems are encountered if the pump is indeed too large?
