I just ran another set of tests:
Salifert #1: 1350
Salifert #2: 1365
Red Sea: 1460
I also ordered an ICP test so we'll see what those results show. I'll run my tests again the day I take a sample for the ICP so I can compare with what it shows.
Is there a way to test the solution that I'm dosing? Now wondering if maybe I mixed it wrong. I'm going to mix a fresh batch just in case.
