Yeah I don’t know why it didn’t work.
Give me 20 min and I will send you nitrate phosphate and ph.
Her is the tank.
So, the first thing that needs to happen is you do a complete GHA cleanup. You’ll need to siphon as you go. You’ve got to get it down as close to rocks as possible. For coral frags that are covered, if you can remove from tank and do peroxide (follow Kev’s measurements exactly, but for a gallon of water that you have in a container/bowl to soak frags in - that would be best.
Then put frags back in scape.
I’m assuming no water changes were done during Spring Break? Either way, do a 50% to ensure you get all the loose GHA that will be all over after you scrub/pick out.
Once all that is done, let’s see the tank again. I don’t think you should do a 3rd treatment. I’d rather see you bump up CUC crew significantly as they will eat it if it’s short. Your’s has been consistently to long for them to tackle. Even a tang won’t want it that much.
In addition to CUC, we should go, over all the products your feeding fish and corals and see about adjusting. We need to get to root cause.
Send us a list, how much you feed and how often.
Stop amino acids or anything like that for promoting growth.
We will,figure out, but at the end of the day, you are going to have to put in the work, all the way.
I would NOT dose entire tank with peroxide yet. Not that it’s not an option, but it is not the first cause if you mess up the ratio you could lose everything like Amanda did.
