Hi all,
I have this algae for about a month and i thought scrubbing and having the pump run longer (producing more chlorine) will get rid of it. But no luck so far as it just keep coming back. It feels little sticky on the bottom too. There are spotted dark algae on the side wall too. I have cleaned cartridge filter couple of weeks ago. I was about to start SLAM but thought of get lesalie's opinion. They said this is black algae and since my pool is 12 years old i have to re plaster the pool and this is the only way to get rid of this algae. Below is the today's water chemistry. Can any one please guide me to get rid of the algae.
FAC - 1.5
TAC - 1.5
Salt - 3300
CH - 220
CYA - 60
TA - 80
