what is your tank's pH?

[surfn]

just set up a new pH probe onto my aquacontroller jr. wanted to see what my tank pH was before i started dosing kalk in my top off water.

after i calibrated it, looks like my tank water is 8.1 with the lights on.

That sounds like a good value. I'd like to get a pH probe to go with my AC Jr. as well. I only have a cr*ppy Red Sea pH test kit so I haven't checked mine in forever, and I wouldn't really believe it anyway.

8.1 is a great value. The pH of natural seawater is 8.2. So long as your pH doesn't dip below 8.0 you shouldn't experience any problems. Getting above a pH of 8.4 will also cause problems, so you're in the sweet spot.

when my lights kick on, its always around 7.9, then by the afternoon, its usually up to 8.1 or 8.2..

mine is 8.0 at night, and 8.2 day....

MIne has been ranging from 7.8 to 8.2. I just started running a calcium reactor (can't keep the CO2 bubbles flowing at low output for some reason...). I used to fluctuate between 8.1 and 8.3 (ACIII) before the Ca Rx. I will likely begin adding kalk to my top off soon.

7.9-8.1

I drip Kalk in my topoff with a dosing pump and my PH stays around 8.2-8.4.

I run a dual chamber CA reactor and my ph is 8.2 at the end of the photo period.
