Both tanks are continuing to do well without B-Ionic, but my every-other-day dosing of the two Seachem pH/Calcium buffers seems pretty haphazard. Both tanks have high Alkalinity now (14 and 15dKH) and high Calcium (460 and 470ppm), but the livestock seems fine.
I have been out of ESV's B-Ionic for a full seven days now. It is on backorder and I'll have to wait two more weeks! ARGH! For now I've been dosing with Seachem's pH buffer and Calcium, but it is not a stable system and I worry my tanks might suffer during the wait.
For the past few days, things have been 'odd' and I couldn't really figure out what was the cause. Both of my tanks were suffering from depressed pH readings, to the point that I became very concerned. pH 8.0 for the high at the peak of the lighting period is not good at all.
