Background: I shocked about a week ago to kill green algae, and simultaneously was dealing with tons of pollen coating my skimmer socks an inch thick. The pool water was yellowish but it's sparkling clear now. I've been vacuuming up what I thought was a mix of pollen and dead algae ... but it keeps reappearing. Could it still be dead algae/pollen mix settling to the bottom? Or is it mustard algae? It's not in shady places, and seems to collect in drifts on the bottom. Here are my numbers:
FC 3.8
CC 0.2
pH 7.8
TA 120
CH 150
CY 50
Sat .5
Temp 60F
I know the FCl loss check overnight is the best way to determine, but I haven't done one because I was killing algae before. It's raining and very cloudy now ... can I do a FC loss test now, or do I need to wait until night?
