I have been using the Red Sea all kit and for a while was getting the expected results, around 8dkh. Recently I have been seeing a drop in alk using the 5ml titration. I have added a few soft corals, so maybe that was expected.
I did a 25% water change on my 50gal tank, mixing Instant Ocean at 1.026 in RO/DI, and was getting values around 4dkh on multiple tests. I tried the 10ml titration and got a result of 10dkh on multiple tests.
how could there be that big of a difference between to two titrations, and which so I believe?
I am thinking about getting the Hanna Alk tester, but I still don’t understand why this would happen.
Any thoughts?
