yes. Its a very harsh treatment.

Its quite likely a bacterial bloom, plus some of the die off from the vibrant.
Id stop that and get started on the water changes. as far as less invasive algae tratments, a turkey baster IMO should be first, a toothbrush next. If its pretty messy its ok to take it out of the tank to do it. You can use a light hydrogen peroxide for easy to kill algaes, rinse and drop it back in the tank.
sounds mean but ill explain. it doesnt matter what it is generally, the cure is usually the same. Time and basic cleaning. this stage is also time to reevaluate your clean up crew.(and double check feeding) if you scrub problem spots theyll keep it mowed down in most cases. if it hangs on for weeks and months its time to worry.
