My pool is approx 18 months old and I am about to have it acid washed for the 3rd time. The finish is pebbletec pebble fina.
Long story short the calcium hardness steadily rises until I get calcium buildup that looks like white scale marbling all over my pool.
The tap water in my city is 200 out of the faucet but it keeps rising 15-20pts per week without fail.
I keep my PH at 7.5-7.7 (sure it has been at 8.0 for a few days, im not perfect, but i balance my pool 2x a week)
ALK runs approx 80-90
Calc harness 300-550 (once i got to 450 i drained it 30% and filled it back up and it went down to 300 then slowly rises again).
CYA 45
Chlorine 2-4
I do not shock the pool I just let the SWG control the chlorine via the iChlor. I occasionally add a small amount of Alkalinity up and Scale-Tec.
my PB is totally stumped but he thinks the applicator of the PebbleTec maybe responsible. He said based on the temperature outside at the time of application they add a certain amount of calcium to get the product to a proper viscosity to apply it. He thinks they maybe "over did it" on the calcium and now its just slowly over time leeching out through the plaster. I really have no other feasible ideas, nor does my local pool store or the company that balances my pool.
Anyone have any ideas?
