I've have what I believe to be a pollen problem that has carried over from last season. All my numbers look fine, my ONCT last night was 0 loss, 0 CC, water is crystal clear. BUT I sill see what I believe to be pollen accumulating on the floor (brushing just slightly near it has it pop up off the floor instantly).
I just had a new DE filter installed replacing the 18 year old one that I inherited with the house (built in '97). So now I'm asking myself, why isn't the pollen being filtered out? It is always accumulates in approximately the same spots. Could this be a flow issue and I just don't have enough jet speed to push the pollen into my filtration system?
I did have green algae when I opened up but I performed a constant SLAM until I passed the ONCT but even during the SLAM, I saw it accumulate over a few days. Not sure how to handle it.
For S&Gs, last night I slammed my pool:
CYA 40-50 (it's hard)
ph 7.2 (before SLAM)
This morning it was still 26 with a 0 CC count. So I don't see how green algae could survive or grow (btw, the weather has been cold (mid-50s/low 60s) and overcast here in NJ, so it's not even great weather conditions for algae to grow).
