Marc, Does your AC3 test those parameters, or do you test every other day and manually record them? just curious.
Looks like he hadn't tested for a month. Everything looks stable though. At least month to month.
I test whatever is questionable at whatever time I feel the need. Such as alkalinity. I've been testing that just about daily or every other day trying to find the sweet spot. Then every few weeks (or monthly), I test every parameter specifically to update my spreadsheet numbers. I have a bunch of test kits and vials that I keep contained in a big rubbermaid storage bin.
