That's a toughie to be sure.....depending how things went, easy to see why the corals might be "stunned" as a result. Some folks get way worse side effects than that.That's a lot to unpack and I'll take all of that to heart. There was one thing that happened to the tank, a major bryopsis breakout. I finally got it under control and I've been dealing with all of the die-off from that, and in doing so, I think i may have given the tank the fuel for cyano. Haven't identified it, but just going off of Google photos. The last time I tested numbers was before I finally got rid of the bryopsis 2-2.5 weeks ago. I haven't exactly done anything the conventional way, which I guess I should because I want the tank to be successful.
I would give it at least another month or two before you have any expectations for these corals.
If you feel like the tank is stable and ready for it, I'd suggest getting a new coral to judge how things are going.....a canary in the coal mine, if you will. As long as things are peachy in the tank, the "new guy" will flourish, giving you a better current benchmark on the tank. If you aren't correct about the tank's readiness it could be another blow to the confidence tho....so I wouldn't be in a giant hurry. Get the tank settled and stable for a while....you and the tank probably need more time to forget about that bryopsis battle. :)
Cyano is no fun either, but can usually be siphoned out and otherwise dealt with more easily. It can also grow back really fast too and CUC doesn't really touch it, so....it ain't great either. :D
Keep up the good work!
