Hydrogen Peroxide Dip

[Hallowhead]

Howdy,

Quick question, I have purchased some new zoa's a times back during the cherry coral live sale. I hydrogen peroxide dipped them for 2 minutes in 3%. I thought they'd all be open and thriving by now.... they are not. Two of them finally have one polyp each open however, one... which happened to be my favorite and was a FAT frag has not opened and seems to keep shriveling however, I can see the zoa through the skin of the closed poly.

I thought hydrogen peroxide dips were safe?

How long ago did you add it to the tank and did you dilute the hydrogen peroxide??

I was told you didn't need to dilute it and about a week ago

If you don't dilute it 2 minutes is a long time, as you can see peroxide is actually pretty harsh and can kill coral. The only thing you can do is wait it out at this point and see what happens. I wouldn't use peroxide unless specimens are taken over by alge as peroxide is efficent at killing alge but can be pretty hard on coral. I would use a 50/50 next time and maybe only for 30 seconds. They will probably come back just give it time
A picture might help

Noted for the next corals that come in.

Just keep blowing zoas with turkey baster to make sure the polyps are free of a very thin crust that can grow over them.. Not sure what it is.. But it can restrict polyp from opening.. Usually when they close this long collor will be way off when finally open.. Will heal in time

Bayer dip is good.. I iodine dip for bacterial .. And like stated 50/50 for any algae on plug.. Check plug for any critters .. Nudis .. Vermithid snails .. Zoa spider..

 

[Ben little79]

I have had them close for a month before.. As long as polyp is still visible its alive..

I agree with the advice already given - I use 50/50 dilutions of hydrogen peroxide in tank water, and dip for 10 minutes, to kill algae on zoa plugs.

At least until I discovered flucanozole, now I dont have any algae problems

I have since turkey basted each zoa pretty thoroughly and definitely noticed some debris shoot off. I know I have a gha or dino issue and they're crusting over the zoa's. I have to be more adamant about removing the growth. Hopefully my nitrates / phosphates come up!!

In my peroxide threads zoanthids are listed as the most tolerant corals to peroxide

That long at undiluted 3% is a new record. Agree I think it will come back as long as other colonies in the tank are maintaining low dynamic profile and spreading, vs long thin separated stalk zoanthids which are on the way out. If the tank itself is promoting zos vs just letting them remain, adding polyps, that one will likely live.

I used to put undiluted 35% on mine with a dropper, it never killed them ever. Nowadays I wouldn't dip in peroxide

For $ zos it's dental surgery for my specimens. Target work. A dentist doesn't use an angle on my gums they use it on the enamel, so my zo frags are debrided clean with a knife, algae free, then peroxide as a dropper only on non tissue areas that used to have algae.

for coenenchyme inclusions I just pick them out with a tweezer, detailed work since the polyps themselves don't have algae/ need to be contacted with peroxide

I've seen ten thousand zoanthid + peroxide treatments and of them all maybe one frag died

This is reassuring. Yes zoa growth throughout the tank. I am at a low time for growth right now as my nitrates are pegged at zero. So I am working on getting that off zero with a little more aggressive feeding and I added a fish.

Well I lost one polyp completely so far. It happened to be my favorite zoa... Very upset about it - the other polyp is on its way out!

Will never do full hydrogen peroxide dip again 50/50 only

 

[Hallowhead]

Or even just spot cleaning

 

[Ben little79]

Sorry to hear that..We have all lost polypsim sure. I lost a small holly berry polyp that i spent weeks trying to save.. It was a good fight though.. I learned so much about treatment during process. And i implemented those techniques in my coral care program.. Sorry bout your polyp .. I feel your pain

How is it now was curious to see pics
