Thanks a lot, I'll put some of those snails in my tank.GHA is mostly a waiting game, keep up on water changes, run gfo, i would change it maybe once a week for two weeks and go to two weeks per change after that, and manual removal on each water change. I've battled what i thought would never end with bryopsis for 4 or 5 months before i found a solution, when you hit that mark, it's an amazing feeling to feel like you won. I was set to throw in the towel and shut down, my last ditch effort worked. It might take you 2 or three months but it will get there. Maybe try a mexican turbo snail or two to help out.
