dipping zoa frag into hydrogen peroxide

[BeachVacationer]

I've got small pieces of zoa frags with persistent algae on them. I know hydrogen peroxide will get rid of that pretty quickly. I'm wondering what dilution and the length of time to dip the frags without harming the zoas. Has anyone tried this? Nothing eats the algae and It's not spreading to other parts of the tank. It just grows on this frag and I'm tired of manually pulling the algae off.

I've done it for 5 minutes at 1 part peroxide and 4 parts water. It took the zoa a day to reopen after. I've only done it a few times tho, so def do some research. I use it to keep bad algae out of the tank, but it kills most types down to the roots so it will set yours back too I guess. The real battle is won when the frag grows over the plug and chokes out the algae so you want to balance killing the algae against irritating the coral or damaging it by poking and bothering cause that slows down growth.
