PH, when to worry

[79chopperdr]

I am running a 210 sps reef. I use a Geo calcium reactor with a aquarium plants reg. Alk and Cal are rock solid. I know I'm pumping CO2 into the tank and low PH is common. I'm running a air stone in a container that collects reactor effluent then overflows into the sump. This helped but I'm still running in the 7.78- 7.9 range.

I know a lot of sps guys say not to worry about ph. I also know low ph can stress fish.


Looking to find a balance. Thanks!

As long as it is stable and you see no changes in your tank. The reef will tell you quickly if something is wrong by just observing. What is the PH of your Make up water? Mine is 5.0 so I add a little Seachem Reef Buffer to my water holding tank and it keeps me stable around 8.05-8.15. Hope that helps.

Make sure your ph meter is properly calibrated.

I added a air stone to the sump and put the air pump next to a open window. PH started climbing

I live in a newer home, an old drafty one maybe an advantage in this case...

Reef buffer in the ATO will temporarily raise the PH of the tank but the PH of your RO/DI has no effect on the tank at all. I'd be leery of using buffers to stabilize PH. Unless they are being dosed based on alkalinity consumption it will lead to long term problems.

FYI if you are using a PH probe to take that RODI reading it will greatly shorten the life of your probe and the readings will not be accurate.

top off with kalk... and chive on

Never, dont even test for it

KCCO! The air pump yielded some great results. Kalk top off maybe in the future though.

Second vote for kalk here.
