pH for coral growth

I just calibrated my pH meter and found my tank operating at 8.1. That seems a bit low. What is the forums thoughts? Heavily infested coral tank.

400 on alkalinity???? Like, 400 ppm CaCO3??? That's equivalent to around 22 dKh, or 8.0 meq/l - and I don't really think that's possible without really ticking off a bunch of coral. I'd remeasure that! Are you dosing anything?

As far as the pH... sounds fine to me for midday. A tank will easily vary the pH 0.2 between lights on and lights off. My tank runs 8.0 in the morning and 8.2+ in the evening, just for another data point.

Sorry about that, I typed in the wrong number. My kh is directly in the middle of the acceptable band on my water test chart. Forgot the value. Will check it again.

Just trying to figure out why all my hard and soft corals are doing gang busters, but things like copper polyps won't open fully. I use to have to scape copper polyps and green star polyps off the tank walls to see in...now they don't do so good..but the coral is super happy.

Would love to know the answer cause my reef tank is the same way. Can't keep Xenia or green star polyps alive but everything is is fine.

Xenia hates change. Whether it is temp, salinity, etc. change can kill a Xenia. A low pH can cause Xenia to stop pumping. I prefer the white pompom Xenia (aka pink Xenia). It is shorter, fuller, and almost impossible to get it to stop pumping.
