PH At 7.4

[BamboozleBean]

Hello all,
My PH is low, and I think it has been causing some problems with my SPS, it’s a fairly new tank too. Besides and airline outside, what is a natural was to raise it?

More surface agitation? (flow) You might have to bump the Alk with something like baking soda first, but this has been known to help. Make sure your Magnesium and Calcium are well within limits too though. They all kind of play off each other. GL.

i have a similar issue, my ph is at 7.73 and i cant seem to raise it. i have a 220 gallon, with refugium and skimmer.
alk 8
cal 430
mag 1241

i was previously at 7.5 but added an airstone to the sump and aimed the return lines towards the surface for more agitation. still cant get past 7.74 for ph.
