green hair algae on zoa frag

[syngraves]

anyone know a good way to remove green hair algae from a zoa frag? had a algae bloom awhile ago from using tap water when i fist started the tank. learned my lesson switched to RO/DI and got the algae under control. the only spot of significant algae growth is on this zoa frag and i cant manage to pluck all of it off.

any suggests would help tons!

Dip in peroxide. 4:1, RO:Peroxide for 2-3 minutes.

What concentrate of peroxide? and are we just talking the stuff from a local drug store?

[achiro]

I guess I'm asking if you are talking about good old fashion 3% H2O2?

[aguila88psi]

yep, 3% H2O2

[a.browning]

I agree, this is what I do as well.

Can the same thing be done to candy cane and star polyp frags?

[syngraves]

Hmm alright. I'll be giving this a try soon. Thanks for the tips!

I'm interested to see the outcome of this. I am having the same problem with a zoa frag.

It works like a charm. I have done it numerous times with various concentrations of peroxide to tank water and it has always worked for me.

Zoanthids, from what I have read and personally experienced, are by far the most resilient coral to peroxide. Ive read articles where people have done strong doses of peroxide to tank water and forgotten about the zoa being dipped for an hour or more with no detrimental effects. Not recommending it, just an anecdote to show their toughness.

On the other end of the spectrum, certain LPS and SPS corals will react to the peroxide extremely negatively and die quickly. Just search on here for different threads about peroxide treatment, I found a wealth of information on the topic.

Yep!
I would recommend, as normally do, 10% hydrogen peroxide to 90% tap water for 1 minute.
You ca rinse the frag in tank water before returning to the system if you want.
The hydrogen peroxide is the 3% from the drug store.

+1 and let us know what happens

The chlorine in tap water will not harm the zoa?

The peroxide dip worked wonders.

I actually was dipping an acan frag i had and accidently left it in the peroxide dip for about 10 minutes while i was distracted replacing the other zoa frags i dipped. thought i killed it for sure but it plumped up and was happy after about 2 days.

I used my DT water. 3 cups tank water and 1 cup peroxide. algae started to bubble instantly. and about 1-2 days later the algae falls of the frag and you can scoop it out.

i have always done straight peroxide for like 30 seconds. no issues ever

I have two zoa frags in QT I dipped in coral RX then a few days later in a 4:1 3% peroxide solution, 4 min with no algae change over the 4 days after treatment. The algae has not grown in the last two weeks it’s been QT any suggestion on dipping with peroxide or what I may be dealing with, hate to toss them out if they can be saved.


Photo below is a piece pulled off that has been in the solution four days.

The peroxide dip may not kill Bryopsis, it seems.

Yeah, I was looking for some comparison photos to determine the Algae type.

100% peroxide dip?
First time I've heard about that.
Even though it's only for 30 seconds I wouldn't recommend it.
It would kill any of the zoanthids I have here right away!!!
The higher I went was a 50% and the zoas were really affected by the peroxide!!
10% Hydrogen peroxide to 90% water is what I recommend to start with.
We could go up to a 40% Hydrogen peroxide to 60% water, but it could harm zoas, depending on how long and the species we are treating.
We can use tank water or tap water. I like tap water most of the time. I don't think it makes much difference to tell the truth.
When we do the 10-40% deal most zoas will open right after the dipping.
That's what is also important.

I'm assuming you are talking about 4 parts of water to 1 Hydrogen Peroxide, right?

Is that Bryopsis? I don't think so.
