Bubble, in my case, is tricky. I experienced the exact same scenario, Fox Face outgrew the system, and boom! I have greatly reduced by planned removals.
I have water change water mixed, and a brew of DIY Calcium Carbonate spiked with KZ ZeoBak mixed. I then disable return pump, to isolate bubble to DT. Next, I take a pearing knife, Battlecorals Toothbrush, and top down viewer, and pick, scrub, and manually remove from rocks/plugs out of the water for excavation. Inner tank structure, I let the bubble settle wherever. Once I am satisfied, I kick on powerheads and kwt the stuff fly around, using a small fish net to capture and remove bubble flying around in water column. Once that is removed, I turkey baste to dislodge uncollected bubble. I then remove powerheads and scrub, tons of bubble gathers in the grates.,
After this, I am free and clear of all visible, just focusing on 80% removal, as a goal. Return pump back on, dose my DIY Calcium carbonate. I let this run for a few hours, then skimmer back in service. 24 hours later, I repeat to get the additional uncollected bubble, then water change.
Otherwise, this algae symbiotically exists in high quality acro conditions. I see more reefers kill aquariums with products, as opposed to realizing the bubble algae indicates that acros are going to do well. Yes unsightly, but I just tell people to look closer at my colors, and get over it
Afer all, if it doesn't bother me, I certainly can care less if it bothers others, lol...
