I used both Vibrant and peroxide. Small rocks got dipped in peroxide( with zoas attached). Large areas I used a syringe and basted the area with peroxide. At the same time I dosed Vibrant. Had a 70 reef full of the stuff and it’s bubble algae free for almost a year now. You could see the bubbles die from the peroxide over several days. They would get translucent and finally clear and disappear. Vibrant took care of the areas I couldn’t get to.
