Hi all, my xenia has been doing phenomenal until the past couple days. It shriveled up and I noticed that the stalks were basically cut in half in height. My tank is a little under two months old and I already noticed some coralline algae on my rock and I was surprised. I thought that this was an indicator for a tank that was coral ready. However, I do not have a test kit for calcium and alkalinty and etc but I have 0 ammonia, 0 nitrite, 5 nitrate. Other corals are doing well along with fish.
