Can’t get my PH probe to read correctly while in tank. Any tips? - Page 2

As an analogy think of the calerpa as a camp fire which produces heat. The closer you get the hotter it is. Your pH probe is very close to the camp fire. The fact that the windows are open does not really have enough impact to diffuse the CO2.
Get a pH probe with a longer cable or get an extension. Try measuring the pH in the tank perhaps at the point where the water enters the refugium. This may be your highest pH point.

I got the ph probe into the DT and it went up to 7.9.
Much better. Although I’m sure it should go up to at least 8.2 over time.

Seems I really need to do something about getting my PH up before I start adding any corals.

Since relocating the probe to the DT the PH goes from a low of 7.5 up to 7.95.

I think the NPX bioplastics May also be lowering my PH.
