So a cold spell and temp water down to 31 and CSI down to -.30
so I bought some Arm&Hammer washing soda (85% disodium carbonate)
did as per PoolMath and put in 16oz but
ph was 7.7 and does not seem it went up
I dissolved the stuff in water and dumped it in by the return
what am I missing?
thank you
