1st full test in a while.

CSI between -0.3 and 0 is fine. The targets it is giving you should be in the Target column. And it will tell you what to add to get to each target. But, those numbers are ok.

The csi says I'm at -0.04 and the target should be -0.24. How do I get to the -0.24

The csi says I'm at -0.04.


As you add acid to bring down the pH that will also lower your TA

FYI - with all the sunny days & your water temp is probably close to what I am at 90, I use about 3.5 PPM of chlorine
