Hi all,
I would like your opinion please on what is the highest Calcium Hardness level I can have in my pebblecrete pool?
I have seen a lot of conflicting information which makes things all the more confusing.
The TFP PoolMath Calculator says for SWG and Plaster pool surface (not pebblecrete specifically) the Ideal CH is 350 to 550 and Acceptable CH is 250 to 650.
Do pool chemistry recommendations change with pebblecrete as opposed to plaster? The PoolMath Calculator doesn't have a pebblecrete option.
Pool articles on the internet that talk specifically about pebblecrete say a CH range between 200-400.
My local pool shop says maximum CH of 300.
I know that having a higher CH helps to have more balanced water according to CSI which is why I was thinking of increasing it as much as safely possible.
My pool water chemistry at the moment is:
FC 5
pH 7.7
TA 70
CH 400
CYA 70
Salt 4400 (400 higher than the recommended for my SWG)
Temp 27 Celsius
CSI -0.17
Any insight, suggestions and recommendations on my pool chemistry would be great.
