I have 65000 litre concrete plaster pool with a SWG unit and I have the following numbers as per my Taylors kit.
CL=1.60 PH=7.7 TA=100 CH=130 CYA=0 Water temp 16 celsius
My Lsi index is -.42 as this is not too bad as water will warm up shortly. Is my PH high and should I be trying to get PH to about 7.5 but if I do, that pushes the LSI to -.62 which might be getting up on high side.
What should I do push the CH up to about 200 so I can get the PH down a bit?
Thaks in advance
