Small amount of bubble algae, seems isolated to just the plug and side of the skeleton of an acanthastrea frag. I've manually scraped it off a couple times but comes back. I can easily remove the entire frag and dip it. I've seen to use hydrogen peroxide, but not seen anything specific to acanthastrea so a little nervous. Can anyone please confirm if that's what they'd do, or have done w/ their experience? Just the 'typical' dip %/time etc? Thanks in advance!
