I am about to tackle the black algae that has taken up roost in spots in my pool. It all started when the salt cell went out at the start of last summer and the chlorine level dropped to zero multiple times. Not only was the pool store wrong about the diagnosis that my salt cell was fine, they were also wrong that is not black algae ~ I have tried everything they recommended and nothing has worked. I have already read about how to go about tackling this, but before I start, just want to confirm that the pool should be in balance before starting it?
Thanks for any help!
