PH refuses to go up!!
Ok been working to get the PH up for months now. Nothing has worked. Im at a deadend it seems and the xenia is taking it personally. PH refuses to go above 8.1 avg is 8.0 and goes to 7.9 at night.
I drip/topoff with kalk. Airpump running fresh air through airstones in sump to drive off excess carbon dioxide. Alkalinity is at 10DKH Calcium 400 Magnesium 1300 Nitrites/ammonia 0 Nitrates sit at 5 right now. usually 2 or less. (Water change coming up) 90 gal system with lots of flow, with a 10gal refug with cheato, and a 30gal sump with an ASM G2 that pulls a decent amount out. The only time the PH goes up is when I add an alkalinity additive. Usually randly holmes farley recipe. Thats to be expected. But it doesnt stay up. What else could it be????

You are seeing ill effects on xenia at 7.9-8.0 Ph? I would not expect that.
What is the Ph of your top off water (before kalk)? What is the Ph of your water change water?

those numbers are fine
those numbers are fine and I wouldn't be too worried about it. many other reefers have the same ph numbers including myself. Although you may wish to verify that your ph probe is calibrated properly - otherwise, don't mess with the water chemistry. my 2 cents

Ya I wouldn't worry about those numbers. it is more important to keep PH steady (which out are) that getting it higher. 8.1 is a good number and a night number 7.9 is pretty good.

Well maybe you should go with "if it ain't broke don't fix it".
I don't worry to much about the numbers as long as everthing is doing well, and i keep up with water changes.
