i think that zoa melting is related to water conditons, i heard that zoas grow more successfully in water rich in nutrients and macro elements, my theory is that very clean water with 0 nitrate and 0 phosphate could be harmful for zoas. those elements are helpful for xooxanthellas and cellular growth.
Vitamin c is a source of carbon which is one of the macro elements as Nitrogen and phosphates essentials for coral growth and metabolism. This may explain the amelioration seen after the addition of vitamin C I started lately to add nitrogen compounds to raise slightly my nitrate level which was zero as i had the problem of melting despite excellent water parameters Last edited by alexandrie; 01/01/2010 at 02:46 PM. |

How does this explain then that when VC is added, it reduces nitrate, yet improvres zoanthid health & growth?

My idea is that a good carbon source will increase phosphate consumption by xootanthellas thus increasing coral growth and reducing phosphate levels in water.this may explain how vitamin c works.
I think it is all a problem of equilibrium between Carbon, Nitrogen and Phosphate proportion. too low nitrogen will lead to bad Phosphate consumption by cells Too much phosphate is as harmful as zero phosphate etc.. I can t deny the utility of vitamin c in the treatment of melting zoa syndrome. But we don t have the full explanation of its mechanism of action. Last edited by alexandrie; 01/01/2010 at 03:56 PM. |

Have you seen where some are thinking that since VC helps build collagen in cells, this may be the reason for improvement?

I read this in your thread, i know that vitamin c is helpful in building connective tissue in humans thats sure, i don t know if it has the same effect in corals
vitamin c has saved my colonie the first time they melted. a real miracle. |

Isn/t collagen, collagen, no matter what "being" it's in?

Anybody who has zooanthids should also have a UV sterilizer. Zoos are very succeptible to bacteria infections and a UV sterilizer will help control the bacteria in the water. I have seen on multiple occasions the "shriking zoos" problem solved with a UV sterilzer. GET ONE, trust me.

yes
collagen is collagen regardless of the source. Though there are about 20 different types of collagen

A solution that worked in my case
My Zoos had been closed up for a couple months despite 5min RO dips. Parameters perfect, albeit a 10ppm for Nitrate. I like to feed. So anyway I started dosing a reef vitamin C supplement, but didn't notice too much change (a few more opened).
It wasn't until I dipped them in Furan 2. I should have done it sooner, when they started melting. But I hadn't realized the extent of loss until I had looked at a couple of old photos. I lost a lot of time on stuff that hadn't worked. But the next day after the Furan most of them were open again. I'm wondering if the enemy is a bacteria specific to the zoos we don't know about. I'm half tempted to try to culture it. If it's a fungus that would be interesting too, but I think the Furan product is more anti-bacterial than anti-fungal in nature. If it is genuinely bacterial, then it would make sense, seeing as how it got worse after I started carbon dosing. I have since stopped, and hope that whatever bacteria it might have been doesn't rear it's ugly head again! |

I had to search for this thread:

Zoos closing and dissolving???
Only time I had this happen was after a significant temperature spike. Lost a nice colony of toxic lava PEs to melting. Temp went from 78 to 84 over 48 hours. We had a freak heat wave and the tank was small, 40 gal, and in the garage.

Yeah its a pain in the butt to be sure, yeah we are all short on space or at least most are, yeah we want that little jewel in our tank asap looking spiffy. But stop and think about how much money you have invested in your tank in corals, rock and some cases sand. Are you willing to play russian roulette and risk it all? To me a QT tank is a very small price to pay for a extra meassure of insurance. Killing off my QT tank and loosing a coral frag is a lot easier and cheaper than killing off a display that has several thousand dollars worth of collector grade coral! I QT everything other than dry sand/rock! I dip every coral I put in my tanks! My QT tank consist of a 10 gallon Aqueon tank, Heater, Aquaclear filter and a Kessil A-80 Tuna Blue. Thats about a 200 buck investment. Easy to set up and tear down repeatedly. Its great for QTing small fish, Clams of Corals. 200 bucks seems a bit steep, but look at a nice display tank full of collector grade corals, add up how much you would have to spend to replace everything in your tank, then ask yourself if 200 bucks is too much to spend to prevent a disaster and loose a tank!!! A QT tank is the best investment I have ever made in this hobby bar none! |

I've been having this happen recently as I've dialed my parameters in for acros...

Possible treatment or cure
I'm sorry that I didn't take a pre treatment picture but this was a last ditch effort. I had a nice colony of Zoa's that closed up and hadn't opened for 4-6 weeks. White fungus was around the base of the polyps at numerous sites. I read on this forum that survival was limited at this point so I decided to try an anti- fungal medication since there was little to lose. I used API's Fungus Cure (Victora Green plus Acriflavin) mixed at 2x the concentration recommended for fish. I placed the Zoa colony in a small bucket with the medication and a tiny pump for 30 minutes. I then rinsed the colony in clean tank water and returned the colony to the tank. Literally, with 48 hours, about 80% of the polyps re-opened and have been open for the 6 weeks since the treatment. There has been no return of the fungus. This is only a single case and not a "study", but if you have a Zoa colony that is "on the ropes" give it a try. Thank you.
