[reefwreck]

210 mixed reef triton 44 sump growing new refiguim running gfo and carbon mixed
dosing nothing
alk 10.2
cal 500
PH 9.41
what can i do to bring PH down just went from 8.4 to 9.4 in 3 days

lol

read this thread and add another "test error" to the list

It definitely is not real.

How are you measuring pH?

Try testing your pH again. I don't believe that pH is possible for your given alk and calc.

Hey reefwreck fyi if you are using a pinpoint pH probe I have noticed when my battery is getting low it will start creeping up on value. Normally 8.3-8.45 but will start reading higher and higher (happened several times now). Soon as change battery out it will be back to normal but not sure what your using for pH testing.

I'd recalibrate it. If you never did, pH probes don't come precalibrated. Double check that it reads both pH solutions correctly after calibration, and ensure the pH is being measured with the temp probe in the same solution (including the calibration solution).

it was calibrated when I got it but will recal and see if it is off

what is the optimum PH value for reef tanks for stability and growth?
