I'll have to check the pH level...not sure. we had the pool water checked by a pool place last week and they had me set my salt chlorine generator to shock mode and said that after that we should be good and after doing that, the water cleared right up.

I didn't weigh the amount of DE that's currently in there. There originally were about 6 scoops of DE in there. The scoops are small and each scoop weighs about 0.33lb so I have about 2 lbs in there. When I did that, the pressure was too high, so I bumped it, backwashed it, bumped it, backwashed it and after doing that, the pressure got down to normal. In other words I probably have at most 1 lb of DE in there if that.
When I actually weighed out 6 lbs of DE, it was around 29 scoops. maybe my pool isn't filtering properly since there's not enough DE...i don't know... is there a way to know that?
