I have been using Salifert Cal and Mag test kit since day 1 (early 2021). Matches the last ICP test results last year. For the past 1-2 months, my Cal and Mg remains high but stable ~490 and ~1480 even with min dosing. 10mil AFR, 22mil Soda Ash, 5mil Ca and 5mg Mg. Alk stable at 8.5. I start to suspect the test kit have gone bad. I ordered a new ICP test, but results won't be back for a week plus.
I run the ca test on fresh batch of TM Pro salt mixed to 0.026. CA is ~500 versus it should be 440. I run the test twice. Now i'm not sure whats the real Ca and Mg value.
Is the test kit gone bad a possibility? Corals seems to be happy, and coraline algae is taking off. I hope the the ca and mg is not dangerously low.
I up Ca and Mg to 12ml while waiting for ICP results. I probably should get new test kit. Any recommendation? Hanna versions seems to be as complicated as the manual test kit. Now sure the value there.
