I’ve always had my pH highs and lows at times I thought were wonky. No amount of aeration or altering of refugium lighting schedule, or anything seemed to change it.
pH highest vetween 6-7 PM and lowest between 7-9 AM.
Finally rigged my broken IceCap Kalk reactor into service again and tweaking to get alk where I want it (incidentally stabilizing pH to a much tighter and preferred range).
Pre-KW
Graphs look similar going back weeks. So, basically swings but consistent swings.
Post-KW Reintroduction to System
You can see the right “swings“ with an uptick as I tweaked config further.
The new tank will finally have its alk/pH pegged like my original tank. Sigh of relief.
