H202 dipping favia ?

[xiholdtruex]

have a frag plug that has developed some algae on it. Very light strands of hair algae. It is a favia coral. Have had many reefers tell me it is ok to dip it in h202 to kill the algae. Has anyone had any experience dipping favia in peroxide with good results?

I have not fully dipped my favia, but I have squirted h2o2 around the bases or in the algae areas. Helps control it. Never had issue so far with the corals reacting poorly to this.

I'd be scared to dip the entire coral in peroxide. Maybe try a toothbrush and scrub the plug.

agreed, don't dip the nonoffending areas. use dental procedure, use metal precision tools/rasps/tiny knife to debride the algae off the septal ridges/areas without breaking them off, then at the end rinse those areas in sw to dislodge all bits.

then use q tip or other creative spot deliveries to apply peroxide to the cleaned areas then a quick rinse in sw after, its amazing how much dentistry translates into substrate management in reefs Ive found. if the areas are too fragile to rasp then spot apply the algae outside of the tank in some creative way/rinse off it'll kill the algae. Ive accidentally spilled 35% on my brain coral before/didn't bleach it as I rinsed quick for safety but I wouldn't dip flesh areas on purpose

The issue I am having is It looked like it was a dying plug. One little polyp survived and the algae seems to be growing over the rest of the coral frag.

would you just let it grow and maybe it will take over the algae?

lemme see pics, I think we should kill the algae it uses both chem and physical means to prevent new growth from the coral

agreed that's a unique case, its mostly covered and if im not mistaken that's bare skeleton on the top, its only ringed in polyp flesh right? still cool find, what fun is regenerating easy frags. the only real work is 90% loss ones. a well-fed brain/nitrogen positive mass adding status would cover that frag back in a year easy. try to tweezer off as much as you can without actually scraping I agree its so small any scraping will hollow it, pull off the algae outside the tank in my opinion as much as poss. dab the bad areas with a q tip and in my opinion don't try for a 100% kill on first go

kill the algae in the center fully and if you have to leave a little algae abutted next to the good parts that's ok to catch n detail on round two, these are just my opinion others would have other ways. some would dip, if you put that in a diluted dip it'd prob work as well without harm to flesh, the other way simply adds detail to avoid flesh contact as much as possible
