Found bubble algae when I came home....

Bought a zoa rock a few weeks ago. Today I noticed a black algae ball on that rock. Do I need to be concerned and what should I do?
 
You can pick it off just don't break the bubble. Pull the rock out when you do it if it bursts you can just run the area
under luke warm water to rinse off the spores
 
I took the rock out of the tank and pryed the bubble right off the rock and the bubble stayed in tact. Looked all over for more...couldn't find one. I think it was from the LFS.
 
i hate bubble algae. It commonly forms on the frag plugs etc that you can't see at the LFS but after you bring it home - starts to grow (even after dipping).
 
You can get an emerald crab or two as well. They really work, I have 2 in my 28G SPS tank. The only place I get bubble algae anymore is on the casing of my MP10 pump, where the crabs wisely wont go.

Many of us do believe emerald crabs do a good job but they do pop the bubbles and don't have a chance to eat all the spores so all they do is just keep the BA in check.. it's a catch 22.. the other thing is many of of say is a crab is a crab. and all are opportunistic feeders... Emerald crabs are omnivores and you always run a risk of getting a rouge one that will eats corals.. I have 2 in my sump that I found having a nibble on some zoas in my DT

I keep a 1"x1" sheet of nori in the tank for him. he usually eats it within a few hours. he goes nuts when he sees me putting the seaweed in the tank. starts reaching & trying to climb the glass at me putting it in. keeps him fat & happy & keeps him from eating my frogspawn & acan that he loves to sleep next to.

From what I read about peroxide dipping is to only submerge the rock the frag is on; not the frag itself. I believe you dip full strength as well.

You can dose your tank with peroxide too but I have learned it interacts with other chemicals in a negative way. Example: While dosing peroxide I had a bad cyano outbreak and added Chemiclean. I woke up to a tank full of snow and all my Caps were dead. I ended u doing massive water changes for a few days.

The only time I dosed the tank with peroxide was when I had Dinos and it worked after 9 days with a combo with a 3 day light out... The only best way to rid the tank of BA is to manually remove or as I stated with emerald crabs with a catch 22 and a risk of a rouge

You can dose Vodka or vinegar to get rid of it but it will take longer obviously and may get worse before better.
 
Another way to avoid the problem is to re- mount all frags you bring home (which assumes the coral is something you can remount) I currently have bubble algae in two tanks, and that is how it arrived- on a frag plug, but so tiny that I didn't see it immediately.
I am fighting it off with manual removal, but it takes time. Both tanks are nanos, in a larger tank, as opportunistic (translation: nasty) as emerald crabs can be, they can at times be the best option.
