PH Monitoring

[Tom R]

I use a ProfiLux controller take a reading of my PH every hour. The ProfiLux then produces a graph that shows me that for the last month my PH troughout the day goes from a low of 7.95 with the lights off to a high of 8.20 with the lights on.

I don't check mine in routine, but I do notice that it goes from about 8.1 to 8.4 thoughout the day.

I have a Pinpoint monitor, so I check it every time I walk by it.

I also have a pinpoint monitor and check it walking by, it goes from 7.9 to 8.2 most days. If my alk is in check it will stay a little tighter 8.0 to 8.1.

I used to have pH problems all the time, until the day I threw my meter away. Everything has been fine since. I find the important thing is healthy fish and corals, not a value on a meter. Regular water changes, and routine tests of Ca and Alk keeps everything stable, I don't feel pH is a required parameter unless something is visibly out of whack.

Don't routinely monitor pH either but something maybe to keep an eye on if starting up a Ca reactor.

When I'm not working - my 3rd monitor is acting as a HUD for all my reef parameters that I monitor with my controller. If I don't run a calcium reactor, My pH stays fairly "regular". When there are windows open in the house, it shoots up to 8.2 as you can see. It's a bit obsessive, but like I said, something to look at when not working.

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".
