Was reviewing the Pool Math calculator after seeing some comments on CSI numbers which is a term I am not very familiar with.
These numbers have been pretty steady over the last couple months with PH slowly rising to 7.8 and then I add a little MA to bring it back down usually targeting 7.4. Adding a little bleach each day. Normally a little over a gallon a week. Pool is new last Sept. and I have never had any issues, water has always been clear. I figured everything was good. Then I started reading some comments mentioning CSI.
Over to Pool Math and per these numbers with a 70 degree pool it gives a CSI number of -.87 which it says is dangerous to my plaster. I have mini-pebble stonescapes, so does this apply in the same manner? Playing with some numbers raising PH to 7.8 gets to -.51 which it says is borderline. Should I leave PH at 7.8? raise CH?
Any suggestions for how much concern I should have with this CSI number, or what I should be looking to change to adjust the CSI number as we head into a Texas summer?
