imisky's 30g custom tank

DCDN the corals are reacting much better than they did under my MHs imo, i just have to fix the alk/ca swings before they'll color back up again but thats only a matter of time

Lee im not sure whats going on with my pH, ive tried about everything and the result is the same. Though just like yours my pH probe is 2 yrs old and would probably benefit from the change. Its just a little crazy that i am getting a swing from 8.2 during the day to 7.5 at night...too much corals not enough O2
