Recently purchased house with pool.
Uses chlorine tablets via inline dispenser.
tested at Leslie’s… yes I know I failed TFP!
Phosphates was through the roof. >4000ppb
CyA: 150ppm
pH: 6.6
FAC: 2.8
TAC: 3.1
Was suggested to drain some water
I drained more than 1/3 and achieved and stopped using tablets.
Used phosphate remover- stopped using.
Used sodium hypochlorite (12.5%) instead of tablets.
Phosphates: 1,500
pH: 7.8 (Rainbow 78 test)
Chlorine: >3.0 (Rainbow 78 test))
Alkalinity: 140
Rainbow 78 test suggests I need 1.5pint of muriatic acid based on acids demand test and high alkalinity.
I’d like to convert to the TFP method but want to use up balance of hypochlorite I bought.
Is it safe to use muriatic acid if I have a dark blue (not quite blalck) plaster pool?
I don’t want to bleach this thing.
I also worry the calcium was out of whack as I kept finding plaster material in bottom of cartridge filter.
Is this recoverable and ok to get the muriatic acid going in it?
Is rainbow 78 test kit ok to use for time-being?
