I have black algae growing on my pebble tec and the tile and the white floats connected to my pool sweep.
My readings are TC 9.5ppm
TA 100
CH 40
CYA 100
Water is clear, no smell. I initially had it in a few spots. I put black algae killer in it over a month and scrubbed the 10 spots i could see it for over hour off and on. I thought it was gone but now I'm noticing it all over probably 200 spots all over. Too much to scrub off. I'm thinking I need to drain pool and have someone come in with acid and scrub off. Help
