I just received my first ATI water test report for a 1 year old tank and discovered my calcium was at 520 which is considerably higer than the 440 I calculated using an API kit. I had added calcium chloride a week befor the water sample to raise the levels up from 360, not realizing the test kit was reading significantly below actual.
My alkalinity test using the Hanna Checker (HI772 checker) also gave me a much different reading than the ATI test. 7.83 for ATI and 8.40 for Hanna. Not sure what's going on here either.
So, before I continue with any tyoe pf dosing, I need to get control of my measuring devices.
Any suggestions?
