Low pH in tank.

[cba191]

I woke up to a minor alarm regarding low pH. It was 7.1. Has anyone put a bubbler in the return chamber to raise pH?

Yes, but in my case, I pushed the air through a CO2 scrubber before the air stone. CO2 in the room was too high and if I just pushed the air in, it would've just lowered pH even more.

That is almost certainly test error unless you added a bunch of acid somehow.

I’d recalibrate before anything else.
