Not sure what's going on. The blue tenuis continued to lose tissue so I have had to cut it up. I took one frag off and the cut the branches that were showing stn off the main bulk of the coral. Was one of my best pieces, it was so blue. Now, to make things worse, I'm noticing stn on a couple other pieces. All tests performed couple days ago have me nothing to be concerned over, and things from what I can see from records have been stable. I am going to stop all color elements as this has been my latest addition... Even though i have been under dosing. The other thing my be the emporer angel? But I would just really expect him to inhibit PE, not cause stn.
Other corals look fine, some better than ever.
