I have 2 PH probes.

The first is in my sump and controls my system PH and the second is mounted in my calcium reactor and controls my CO2.

Both probes are controlled by my ProfiLux controller and it constantly reads the probes and reports their status every 3 hours (this can be adjusted to as often as you want).

LOL I did the same thing, and it really did solve my problem! My tanks like to run at 7.8. No matter how much I bump up my PH with chemicals it is always down to 7.8 the next day. Soooooo I dont check it anymore and its all good!

I'm with Brad on this one. My Aquatronica measures pH all the time. When I first got it I freaked out some about it because it never goes above 7.6. The tank seems fine so I just ignore it (plus no matter what I try it always goes back to 7.6).

Anyone who answered the poll as "it never changes" has probably not measured it accurately enough to see what is actually happening. There is a 24 cycle based on the lighting and it is VERY unusual to find a way to hold pH steady throughout the 24hrs.

Here's a challenge...someone show me a 24hr graph with hourly readings of their tank pH that stays flat.

As for what to do about it. As mentioned, the answer is "don't worry about it".

I do not monitor my Tank PH but do monitor my Effluent of my CA Reactor

The answer is "not at all" as in I dont check it.

I seldom check, but when I do: 7.9 (morning) to 8.3 (evening)

Your supposed to check it?????
