My readings this morning:

FC 3
pH 7.8
TA 80
CH 250
CYA 60
Salt 3100
Water Temp 86
CSI -0.07

Water is clear. Pool looks good. Working on getting the CYA and FC up alittle more. However, when I go to either skimmer I find the black particles in the attached picture. Any idea what this is?

Looks like bits of plastic - maybe. Could it be a pool cover deteriorating and dropping pieces into your pool?
