I posted earlier but off another persons post, so not correctly so here goes. As you can see my green BTA has lost it's color and has shrunk in size. My tank is only about 6 months old, a Fluval flex 32 gal reef tank. I added a 207 tank filter in addition to the one that comes with the setup. My Green BTA is very sad, it was doing great when I got it about 3 months ago, and yes way to early to put in the tank I read after I got it. I purchased 2 tank raises clownfish at the same time and one of them decides to make its home in the BTA a couple days later. I have fed it a few times when it's mouth was open a couple of times weekly small frozen shrimp. I used some Bright well A and B as directed on bottles a few days ago. I saw some red film algae so I cleaned the tank yesterday using a a new bamboo tooth brush on the rocks and did a 5 gal water change. I checked all the parameters and all were good except for the magnesium which it high at 1440. Is there anything I can do to help my Emmy?
