I have a few acros and a few monti caps that are doing well. Whenever I get a new frag, it typically doesn’t do well. Tank parameters have been stable for a while now. Over 3 months. Recently got a trident which makes it much better and able to watch, calcium reactor is dialed in well. I am at a loss on what it could be. No I haven’t done an icp test cause of the monti caps were dying it would have happened already. I have two tanks connected to the same system and one sump. The other tanks fine and no issues at all. Any help would be great.
