Green on bottom
18ft round above ground 48" water depth with vinyl liner
FC 6.0
CC 0.0
PH 7.3
TA 60

Added bleach and brought chlorine to 15, held for three days, have been cleaning pool bottom and sides daily. Still getting collection of green in bottom. Appears I have not killed the alge? Any help would be greatly appreciated.
Thanks in advance, have learned alot in a short time from reading other posts.
