While testing my pool the last month, and using Jasons Pool Calculator, I have notice as the water temperature drops, the CSI index drops as well, if you let the PH rise, it somewhat couters the drop on the CSI, I remember reading in almost every post concerning PH that you should never let it go above 8, right now my PH is at 7.9. Also Because I live in El Paso I have high Calcium Hardness my tap water is 250, so I always have a High CH number, it is managable at 500, also with this in mind I did plug in the "ideal" number for CH for my SWG (300) and if I had that number for real the Pool Calculator says my CSI would be -.31 with water temp of 40 degress, but if you bump up the water temp to 80 its at .06, so my question is, when the water temp is low lets say 35-50 degress can you be more liberal with your CSI indexes??
