I have been battling an algae bloom for 2 weeks now. My numbers are as follows:
Chlorine: keeping it at shock level of 20
Calcium: vinyl...don't test
OCLT 20 night, 0 morning
The pool isn't green anymore, just cloudy gray. Running my sand filter 24/7 on filtration setting, backwashing as needed, brushing and vacuuming daily. Water refuses to clear up.
Is it possible for this to be mustard algae? Maybe a filter problem? Just being impatient?
Any help is appreciated.
