Not when the monti they are attacking is one of these:

or sometimes on the underside of monti caps.

They hang around at the edge of the tissue. They are really small, so you have to look carefullly.

Found these today. They are actually really small in comparison to other nudibranch's i've seen. 2-3mm in length, which i why i've never rally noticed them. Going to try an nuke them and any eggs with a iodine dip. May even have to resort to a copper dip, if they come back. Layton

I had those coral eating bastards too!! Got rid of them though. BUT i think i found some monti eating nudis today! They'll be gone tomorrow

What will be the result, and of what?

They were questions for you to answer so i can try it. Tell me what you think will happen? Layton

That is primarily what the skimmer does, remove phosphates. Nitrate can be processed by live rock. He doesn't use phosphate remover, because of the iron thing. I've been reading more recently on Bomber's methodologies. They are simple and make complete sense. In a sentence, don't let the crap fester and decay in the first place. Get it out before it becomes a problem, then you don't need all these "band-aid" products and methods to achieve results. He also uses UV to keep phosphate (and other organics) unbound, and "simple" so that they are more easily skimmed. Layton

It surely does, and not just some, it's a lot.

Probably time to post this: http://www.zeovit.com/forums/showthread ... ge=1&pp=15 I had a good laugh at this when I saw it. Apparently i'm 19, a distributor of a competing product, i'm ignorant, i think that zeo doesn't work, and are hell bent on telling everyone it doesn't work. I am closed minded, big headed... wasp, the first post of yours above completely missed the point of the reefcentral thread. Some might say it was a closed-minded assumption. This is what i don't get about zeo people. Just like everyone else, they have no proof of how zeovit really works, yet they are so quick to discount speculation, with no valid challenges which i have seen, while their theories have gaping holes? Then claim that everyone is just "zeobashing" What are my nutrient levels again? I forgot. How many brown acros do i have? Maybe you can jog my memory on that one too. Layton

Because I don't think anyone here has access to the equipment require to test this.

Actually that is all fact. It does occur, it's proven to happen. The speculation come when making the connection with the zeovit system. There are bacteria (which apparently are quite common) which take ammonia, under aerobic conditions, use it as an electron donor to reduce iron. By reducing ammonia, you reduce the rate at which nitrate is created.

Which speciation of iron? Does it need to be chelated? What do you mean by unstable in an aquarium? What if i dose it at a rate base on the study by lars, later confimed by Habib, consistent with the leach rate of the zeovit zeolites? Layton

According to speculation on the thread. Ammonia acts as an electron donor for metal eating bacteria to reduce iron (change it to a different speciation). Reducing ammonia before oxidation, means less nitrates being produced. It appears that iron can explain almost all of the processes which are visibly occuring. Layton

ok, i'll give it a go. Add an iron chelate. Make it bioavailable through bacteria. Iron is free to bind to other molecule (it is actually not specific to JUST phosphate) Still sounds very familiar? Did I go wrong somewhere? But what it doesn't explain is: Nitrate reduction. Colouration of corals despite indicators of high nutrients. Occasional coral losses. Layton

Tell me what to dose how much and i'll do it in a seperate tank i am currently setting up. I'll let you know what happens. Layton

What critical part am i missing? Layton

How do you know? What makes you say that? Layton

I though zeovit was unique? No other system like it? Sounds like that theory is based on making iron bioavailable. Hmm, that sounds familiar Layton

Don't worry, I get as much entertainment out of your posts too. What did you find so funny. And what were you're rational points? Anything related to zeovit is pure spectulation (any theories, including any you may have wasp). The simple fact is is that there is no proof that zeovit does anything. That is not to say it doesn't do anything, i know it does, but still there is no proof it does. Layton

How come? Coral growth is not well correlated to coral health. Layton

I agree. The entire thread is pure speculation. Although it is based on facts, there is no hard evidence, or proof that zeovit works in this way. But is sure is interesting reading. I don't think the iron is particularly toxic to zooxanthellae. What i think happens is the algae is provided with excess food. Some corals are less effective at regulating their zooxanthellae (corals can regulate food the the zooxanthellae to a certain extent), so in response the the oversupply of food from them, they expellel them. Maybe it can appear "toxic" to come corals. But not to the zooxanthellae. It's food for them. Not having read the study. I would not know whether what you're suggesting is correct or not, it depends on how it was carried out. I don't know how you can claim this yourself? Maybe not quite that easy. What speciation whould you add? Fe(II), Fe(III), an organic complex...? But people chuck iron in their tank all the time. And if I remember correctly some fairly similar things happen. Layton

Offer still stands. My brown corals would be perfect subjects for this. Layton

No need. It has been established already that increased iron can cause zooxanthellae to be expelled: - Metal tolerance in the scleractinian coral Porites lutea. Harland, A. D.; Brown, B. E. Cent. Trop. Coastal Manage., Univ. Newcastle upon Tyne, Newcastle upon Tyne, UK. Mar. Pollut. Bull. (1989), 20(7), 353-7. Which states “Exposure of the scleractinian coral P. lutea to elevated iron concns. leads to a loss of zooxanthellae (symbiotic algae) from the coral tissuesâ€. Are you suggesting that sending a hobbyist a solution of unkown substance, having them dose a certain amount with no ability to test whatever they may be adding, and by looking at the corals, dispute the findings above? The speculation in the reefcentral thread explains a lot of the effects that are seen when using zeovit. I'll volunteer to try if and only if you also agree to cover all coral losses that occur.
