[deller]

Hi and thanks for the welcome. Here are the most current readings which are way different than last night.

TC - >1
FC - 0
Alk - 110
Ph - >6.8 (drops didn't go lower - strip showed possibly 6.2)
cya - 0

Yesterday:

1# bag of 73% Calcium Hypochlorite (powder version) in the afternoon.
4# of cyanuric acid over the past week - yesterday about 2#.
Last night we used 7.5 gallons of 6% Sodium Hypochlorite - which disappeared in 5 minutes.

Pool is 18' x 34' vinyl 18,000 gallons. Filtration system is Hayward and is a cartridge. Pool system also flows through a solar panel.

Next step?
