PH question

[laytonp]

I have a 60 cube and am getting low readings on my PH. I am not sure why, but here are my other parameters.
CA 425pm
KA - 7.4 dKH
NH3 - 0
Temp 76-77.5
PH - 7.94

Everything seems line line except for the PH. Should I be concerned or just watch it?
Also in reading it seems that having a good ripple on the tank surface could help keep the PH in check due to the dissolved O2, and my MP40 does a good job at that. Also all my corals and fish look good.
Any other thoughts?

PH Down to 7.8 is no problem. Mine always runs in this area (7.9 to 8) . Just keep alk in a good range

Are the lights on when you test the PH? Is there a lid on the tank?

lights were on (LEDs). There isn't a top on the tank or the sump.

Your tank is within the acceptable ranges. I'd just watch it.

Thanks for posting this article. It was a good read. I am going to continue to monitor over the next couple of weeks to see what happens.

Try not to chase ph!! If u can open a window so fresh air can enter the room that will help. In newer houses its more likely to have a low reading due to low oxygen levels.

That's one of the factors I think is in play here, except that up until about a week ago it was hanging around 8.2. Then slowly dropped down and is now fairly stable at 7.9.
