Having successfully completed my SLAM last week, I have been focused on monitoring the FC this last week to determine how much I lose each day. Target is to maintain FC between 5 and 7 (CYA 60) and that has been going well. I am losing about 2ppm FC per day so adding 41oz 8.25% bleach to regain that loss.
Today I did my first full set of tests since my SLAM and results are:
Plan of adding a pint of muriatic acid to bring pH to 7.4 - Both my grand daughter and I have had some stingy eyes which I am attributing to slightly high pH?
I think everything else is good except the CH is a little low. Curious what the impact is of low CH? According to pool math I need to add 207oz of calcium chloride to bring CH to 300 (targeting midway on the recommended range of 250 to 300). Is there any reason to target higher or lower than that? Also where so I purchase calcium chloride and what name is it sold under?
