So was out for 3 days and returned to find pump not working and pool yellow/green/brown. So had the pump fixed, adjusted pH, brushed, and put in 5.5# hypochlorite.
Three questions emerged.
1) After one hour FC was 24 and CC zero. Why is CC zero?
2) What is the max FC ok to swim in? (not that I will be swimming, just wondering)
3) On this page it suggests to add DE to sand to speed up filtering. I asked the pump fix person who said since you have glass and no DE membrane, at the the next backwash your DE will be gone. You all agree?
