I have been watching my brain lately, and instead of being wide open , it is rather closed. Just doesn't look as good as usual. I do notice however the brain goes through stages of opening and closing. So is this normal. I am often told that in the community reef the dkh of 12 is the target. My ph is 8.4, dkh at 14, and the calcium is at 460. I use a calcium reactor and co2 with a controller. So what I want to know is why I hear people say they are trying to get their dkh between 12 and 14. Then I'm told from a few that maybe your dkh is high. Isn't 14 a desired point for corals? I notice my ph is always fluctuating and I don't worry. It changes day and night slightly. Can anyone tell me if their brain acts like the one I have. I will give the photo I have of my brain on a good day, and then imagine what a brain at night looks like. I will post a picture of how it looks all the time now in a while. I am not too concerned because all the corals in the tank are lovin the reef. But. . . . the brain is the one coral I wasnt to meet the demands for. Planning to start my waterfall tank so perhaps that introduction of another 151Gallons will give him a jump start. After water changes I usually see every coral respond. Magnesium is good level, I dose per test result weekly.
My Ph - dkh, and calcium. Brain Coral hates me
