I've posted about my cloudy pool before here and was able to clear it up by slamming and it didn't go clear until I regularly backwashed.
The same thing is happening again and again I have what I think is near-perfect water, see below for numbers. This time though when backwashing the pressure does not seem get any lower. I usually have the pump set to about 3000 RPM for a couple hours to skim the top debris and then lower it to ~2500 to continue to filter the water. Once I noticed the water getting cloudy again I boosted the RPMs up to max (3450) and saw that the pressure climbed to about 25. Backwashing did not seem to bring it down much, maybe I didn't run it long enough but the water seemed to run clear after a couple minutes.
I know I should probably do a deep clean but the filter (Jacuzzi Laser 250) has a very small opening and it is in an enclosed shed so I can't overflow it and don't think I can get my sump pump and garden hose into the filter. Are there any other options to try to see if this is purely a filtration issue?
