    I just got a Apex and the PH probe and I just calibrated it and it was a at 8.29 before I calibrated and now it at 8.19 after so it was off a little. does any one have a ph probe? how low does you ph get at night and how high during the day?

    PH drops at night because of the change in oxygen levels.

    Mine usually drops 0.1 at night, but I run my fuge on a reverse photocycle so my chaeto is helping it stay higher.

    Here's mine from last night, fluctuations aren't bad. Just your probe clean and calibrate every 1-1.5 months
