I dealt with a bloom about a month ago. I got a mix 4 kinds of snails and 2 kinds of crabs. It went well, was completely gone in 2 weeks. The work horses were the emerald crab and turbo snail. Now that the ha is gone I rehomed most of the turbos. They are a pain as they knock small frags over if you have them. You will also have to get your nutrients under control or it will just come back.
Make sure to do frequent water changes and siphon out their waste from devouring the algae, there will be a lot! Good luck!
