Here is my present numbers.
CSI is is between 0.00 and +.04 depending on which spreadfsheet I use.
So it seems this is my pools sweet spot.
My question is this...
It seems that my water balance is really great now with pH at 7.8 with CSI of almost zero.
Why would I change this by adding acid to lower my pH to say 7.6 which gives me a much lower CSI.....
I'm thinking not to add any acid until my pH reaches 8
