I'm looking at stainless steel algae brushes. They come in a variety of sizes-- from 6.25 to 18" wide. I'm trying to get rid of some black spots (the dreaded black algae, I fear) in a 1' by 3' section in the deep, shady end of the pool. Would the smaller brush be more time consuming, but more effective?
My current #s are:
Water temp 81
Chlorine 13 ppm
TA 80
pH 7.5
CH 300
