Hi. Big fan of site. I have an in-ground plaster 12 x 24, 8600 gal small pool with screened lanai. I have been following site for a while and seem to have pool under control.
My problem is when I sweep it every 2 to 3 days and a green dust is swept off all walls and floor. Filter has some green in it when I check hours after I sweep, so I do clean it. FC and CC values seem great! I do have a lot of pollen here but it is not yellowish and is on walls.
Hayward super pump 3/4 rated, Waterway PCCF 100 filter housing, but using a Pleatco PA 90 filter. When clean 9 psi non solar and 13 psi solar using 5-4x12 solar panels with valve to use or shut off solar. When pools pump starts I do get air coming out of jets for a few seconds on solar. Also, suction, skimmer and main drains each has their own line to pump with valves to select one, two or all. I us all single item chemicals (I did use Pool School a lot, tks for it!) like 10% chlorine and muriatic acid from Lowes. Taylor FAS-DPD and Pinch a Penny 5 way test kit.
