I generally keep the saturation index as near 0.0 as practical (using the Taylor wheel in my test kit).
Today's test results:
pH 7.5
CH 330
TA 80*
Borates 40
CYA 55
Temp 82
Since I have borates as well as CYA, I correct the total alkalinity value as directed in the testing guide (at least I hope I'm doing is correctly).
For today's example, Total Alkalinity (corrected) = 80 - (40 * .15) - (55 * .31) = 57
Using this value, my saturation index on the wheel is ~ -0.1 which sounds okay.
But is the value of 57 too low since the ideal range is 80-120?
If I need to be doing something differently, please advise.
Thank you in advance!
