Suggestions for my toadstool?

I haven’t seen this open up in months now. Every once in a while I see some green but nothing like what it used to be.

This moved from my old 20 gallon to a 100 gallon about 8 months ago.

My thoughts here are too much flow?

Other side of the tank has torches and they’ll all doing fine. Zoas doing fine as well. Just not the toadstool.

Best way of getting rid of bubble algae?

I’ve got an infestation going on an I keep manually removing it when I can. Seems like I remove a lot then it’s is back in force a week later. I’ve been hooking up my siphon to dump into a filter sock to help stop the spread.

Picture is from before I spent an hour cleaning up the rock.

I’ve got 1 pithos crab and he isn’t cutting it! I’ve got a fox face and he seems to care less about it as well.

Tank is a 80 display with a 30 gallon sump.

Phosphates are near 0 (0.00 to 0.02) nitrates are 0-4, dkh of 8.5. Calc 430 mag 1450.

The numbers have been pretty stable the past couple months.

I feel like I’m knee deep in bubble algae and it is making me want to tear everything down and start over.
