    Hi all,

    I have never measured PH in my tank before, ever. I had all along assumed that if my KH was stable my PH will take care of itself. I am not a CR user. I use dosing method and my KH measurement is constant no matter which time of the day I take the measurement. I am currently keeping my KH at 6.7-7.0 as per the expected levels of AF balling method.

    So is this correct assumption or is there a need for PH measurement? I think it applies more to CR users right? Please do share your thoughts.

    Dont find myself a need to measure ph ever. Think its only rare cases where people will have extra low ph problem lol.
    Anyway, when my cr is off, ph controller indicates my tank ph is at 8.3

    I find ph reading extremely useful for my troubleshoot and indicators of photosynthesis process.

    A low ph during lights off tells me my kH is getting low. Time to test for kH and increase effluent rates accordingly. or can also tell me my wave maker is not creating sufficient surface movement for oxygenation.

    A low peak ph during lights on tells me the useful light spectrum for corals might have shifted causing photosynthesis to reduce. Maybe it's time to change tubes/ballast or maybe light intensity too strong causing photoinhibit.

    A high ph during lights off could means my co2 cylinder pressure is low or ph controller faulty or solenoid jam.

    A high ph during light on tells me photosynthesis is good and the intensity or spectrum is just right for the corals or could it be I overdose on the kalkwasser?

    So in summary, a properly calibrated ph reading on your tank can tell you a story behind the fluctuations provided you know how to read the messages it trying to send.

    Welcome to advance reefing...

    I m only at the noob level of using ph indication during light on to know whether my CO2 got gas or no gas ...:$
