The pictures look like there is as much hair algae as bubble. If your zoa's are on rocks, I'd take the rock out and in a bowl of tank water start brushing the algae off with a toothbrush or some other small brush. Once you have removed as much as possible I'd give the zoa's a bath in hydrogen peroxide. If you use 3 parts water, 1 part peroxide the zoa's will be totally fine. They'll close up for a day or two but no harm to them at all. The peroxide will only kill the remaining algae. I've done it a few times.
I'm just being honest and I'm sure others have opinions but in my experience, once hair algae gets in your sand bed its almost impossible to get it out. Removing the sand and replacing it is sometimes the only solution but I've never used vibrant, maybe it does wonders?
