jblizzle said:What water temp did you put in the calculator? it affects the CSI.
Did you add more CYA, have different lighting, or maybe have CYA you added that is just now showing up on the test? When was the last time you added CYA and when was the previous CYA measurement taken?MonsterPoolMan said:My CH is now 220 (going to *** 5 more lbs) but my CYA jumped to 45!

chem geek said:The reason your CSI dropped in spite of the higher CH is that you used a much lower temperature. In your previous calculation from this post, it looks like you used a temperature of 84ºF to get your CSI of -0.35, but with your newer CH and CYA numbers AT THAT SAME TEMPERATURE would give a CSI of -0.16. At the lower 56ºF temperature, the CSI is -0.41. It's the colder water temperature that is lowering the CSI.
I think it is still a problem.MonsterPoolMan said:chem geek said:The reason your CSI dropped in spite of the higher CH is that you used a much lower temperature.
