Which test to trust on CYA
I tool a sample to Leslie's and they said my CYA was 70. I did the test at home using Ben's kit and saw closer to 30. Why such a large variance?
I plan to take a sample to another pool store soon to see what they come up with.
My SWG instruction says to hold CYA at 60-80 so depending on who is right, I either need to add some or am right on target. I added 2 lbs about 2 weeks ago since this is a new fill .
Any reason I should be gettng such a variance?
