I gave up when I read one guy from Arizona took his rocks out & put them in the yard in the sun for a week. When he put the rock back in the tank it came back. Guess the thing to do is never let it get started?
I converted that tank to a planted discus tank. Worked all issues out, got the fish I wanted everything was great & the tank started to come apart. I was so fed up I found a home for the fish & gave the tank away. Eventually I built a large terrarium on the stand the 180 sat on. It has 10" of water but is 48" tall. The rest is a big stump, branches & plants.
All this was a few years ago & I'm just now putting together a new Saltwater tank again.
Good luck with your new tank!
