Well, I haven't updated this thread in a while. I have some good news and some bad news. The bad news is I lost a few SPS a while ago and I have a huge red slime and diatom bloom. The good news is all the other corals are doing perfectly fine and growing well, and I got rid of the red slime and the diatoms growth speed is slowing down. I also added a few more corals a while ago.
