Yes, I know there are multiple threads about this but my problem is over 4 years old so far I've yet to find a message board or LFS that can figure it out. So let's just say this is a very advanced GHA thread.
Several years ago I started this thread on another board but none of the suggestions worked. The last post suggested as a last ditch effort to completely start over so 15 months ago I replaced the entire setup with a 45-gallon Red Sea MAX E170, complete with skimmer. Replaced all of the rock except a few tiny pieces that (what was left of) my corals were still attached. GHA exploded within 3 months so the LFS came out, drained the tank, doused all of the rock with hydrogen peroxide, and scrubbed it off. That actually worked for about 6 months but it's back and worse than ever. I have had two LFS crews (including the owners) and one free-lance maintenance guy come out and everyone is out of ideas. Nobody understands why I keep getting it and why it won't go away.
Below is the entire list of everything done that's failed to work...
