Hey guys, I posted a topic about a month ago, took some suggestions then almost everything was fixed. My current issue is my brain corals are still not inflating and look pretty poor. My water Chem is:
Tank 250 gallons 90 gallon sump/refugium been up for 2 years, was in a 90 gallon for 1 year previously before upgrading to 230 gal
Ph: goes from 8.1-8.22 daily via apex
Calcium: 425 ppm
Mag: 1155 ppm
My brain corals are not opening while everyone else in the tank has 0 issue opening and my plate corals that had recently bleached, from a light malfunction, are growing back rapidly along with zoas and leathers. So everyone else in the tank looks amazing, but the brain corals. They were purchased at frag nappe and the guy kinda manhandled them. They didn't appear to be damaged, but they are not opening still so I'm wondering if there is anything I can do. I am positive of all the results for the test with the exception of phosphates. I have a phosban reactor going so they should be 0, I also stretched out my algae in my refugium so it can grow faster and increased its lighting cycle. This being said I have read forums on feeding the brain corals to increase their well-being, but I'm curious if the phosphates, if I am wrong, and they are .25 ppm would cause them to not expand and stay shriveled up. Thoughts are appreciated/questions.
