How important is CSI? My numbers look okay (I think you can see them) but CSI is -0.58. Is there anything I should be doing to get that number above -0.30?
 
You have a fiberglass pool. Unless you have waterline tile with cement based grout, low CSI is of no concern to you.
With a SWCG, you want to keep your CSI below 0. If that is not an issue, then turn OFF Tracking CSI in Poolmath.
