I've been tying to leaf rake as much as possible but since I can't see the bottom it's hit and miss with the size loads I fish out. I hooked my manual vacuum up to see what would happen and things went well for awhile. I would let the psi go from about 15 to 20 before backwash/rinse. Now the psi gets to about 18 and I start seeing a solid ray of algae shooting out the return!
I quit vacuuming to filter and started filtering to rinse (I think it's rinse, I don't have a setting labeled "waste") which did really well at first but I don't like dropping the water level that quick. Have I blown up my filter? It seems to run fine in normal filter mode but now I'm concerned I'm just regurgitating algae back into the pool at a lower level where it's not visible.
