I'm running a 24 gallon nano cube with cabbage coral, mushrooms, two frog spawn, a tiger's eye bubble and a candy cane coral a yellow scroll and pulsing Xenia. I am having a real challenge in getting my Ph to 8.2. I've been dosing with reef buffer on a daily basis. My alkalinity is back in line after a significant water change and I have also been supplementing with magnesium. I cannot seem to get the level above 7.2 and that's causing problems with the coral. Does anyone have an idea of what could be causing this or how aggressive I can be with the buffer?
