Hello, since i got my pool 3 years ago there has been a struggle with CH, for some reason it keeps raising to pretty high level, currently at 700.
So some background built new pool, pool vendor handle the chem for few weeks passed to me, i dealt with it for a bit and noticed my pH will increase rapidly, requiring sometimes more than a gallon per week, eventually i hired someone to look after the pool (guy been doing it for 40 years) after i while i noticed calcium flakes, fired the guy CH was over 1k, drain water for a while added soft water, maintained my self and eventually got it down to around 400. Hired another well known pool company that many of my neighbors used, after few months the flakes are back they tried to fight it with acid, that fixed it for a few weeks, but flakes are back CH is around 700. Note when pool gets flakes so do my salt cell. Also when i use the heater that seems to increase the flakes
In my opinion is lack of acid from their part but they claim is my pool finish releasing it, that acid is perfect. Just trying to get you all opinion.
Edit just got some results from a 2 year old test kit: and test strips
Note: pool cleaning company came today and added acid, not sure what else they added (few hours ago)
FC 7.0
pH 6.8
TA 40
CH 550
CYA 20
SALT 3600
Water Temp 93
