20 Chlorine Bottles
12lbs of Shock
FC: 3
CC: 3
CYA: 40
TA- 80
CH- 280
PH-7.4
Pool set for 2 years by a previous owner. When opening the pool it had a tint of green in the deep end. I've shocked the pool 3 times and held 15-20FC for more than 24-48 hours adding chlorine in on the hour. Vacuuming pool every morning when I see what I think is a bunch of dead algae on the bottom. The pool now is clear but not holding FC very well. I've been trying to keep FC at 5-8, however it disappearing. Ran the over night test and FC dropped from 5ppm to nearly .5ppm.
Not sure what to try next?
