Either way, but I'm very glad we talked
I searched for ten mins just now but can't find it
A thread here of sheer desperation, from 5+ tank keepers, with bubble algae so bad the tanks are likely lost....only caused by not acting on first bubble
Peroxide on the cleaned area, after you removed it externally, cannot hurt. Mopping up microscopic leftovers if any is the goal. Valonia is among the invaders that when set in, nobody has a repeatable method for control. Not mithrax, certainly not ATS control, not GFO, not peroxide, they are a true tank risk. Yay to your catch.
Somebody's one off cure in their own tank simply doesn't transfer out to the ability to correct invasions in other tanks, when I find that example thread you'll see what I mean. Any other site has example valonia loss threads too. I'll rank a V infestation as top three riskiest for any reef tank, although minor issues headed off early are no big deal. I too got some red botry in my tank off a frag, I just drained the tank, spot treated, then scraped it off and wiped the area with a paper towel. Never came back
This species is an obligate hitchhiker. When eradicated, it cannot get back in until brought in again. It doesn't have a dormancy period where it comes back later
True clear is clear.
