Help w/zoas melting

[A. Grandis]

Some old saying states that iodine depletion by Xenia would need often replenishing of it in the long run. Skimmer constantly removes iodine. I guess all that would depend on many aspects, but it is something to have in mind. Well, when you've mentioned Xenia I was relating to melting, so...
Zoanthids need some iodine too, and that could be an issue in a small closed system with lots of Xenia. Just a thought.
Iodine (normally dosed as potassium iodide) could be offered and it shouldn't reach excess levels. Iodine also stimulates algae growth! Hard to determinates what would the excess be without testing.
Many don't believe iodine should be frequently dosed and water changes should do it.

Sorry, not to bring an off topic here, please.

That's helpful. I do put in 5ml of Brightwell Iodine once every 10 days. No real method or reason to why and I don't test for I-. I will probably stop this practice when the bottle is gone.
Thanks, Chris

I dose SeaChem's Reef Iodide once an a while, say once a week, very little for the zoas.
I believe the more zoas we have the more chances for the need of iodine in the system. Not a big issue, but I think it helps.
There is much more than that, when we think about the water chemistry, of course!

I use SeaChem's because that's what we used to have long time ago and got used to their products. They work and why change?

I've stopped using the product and noticed a small difference after 2 months. The polyps were reproducing and opening less and the colors were kinda pale, specially some small pink ones.
Not to really blame the "lack of iodide", because there are so many things to play with in our systems, but when I added again the colors came back in some colonies and they opened more. If you add too much you'll see algae growing. Coralline algae needs iodide, like corals (soft and hard).
I've never used Brightwell's iodide, but use other Brightwell's products and like them.

There is a lot of controversy with this iodine/iodide/iodate topic since the mid '90s, so...

When Xenia's iodide uptake is high, the zoas could suffer with the lack of it in the water.
Perhaps you'll notice a slow growth, or possibly unhealthy scenario, of your Xenias/zoas when you stop dosing iodide in the future.

How is the colony doing?

Colony is not well. I have not had the time to pull it and dip in Furan. I increased the flow a little more to see if that helps but not sure anything has changed for the better.

 

[cediss]

I dipped in Melafix for about 15 minutes on Sunday night and so far it looks like the colony may be recovering. I'll keep you posted!

I have had zoas do the same thing. I used a perixide dip and move to a shaded area of the tank. Saved many zoas that way

By no means am i even a novice on SPS but i am learning with my two Monti's. In researching threads about SPS, i remember a thread talking about the ultra low nutrient systems that SPS require can often times hinder zoa colonies. If youre dominant in SPS you obviously know what youre doing there. Maybe the low nutrient system is effecting your zoas. Just a thought to check in to.

One can hope that in the 5 years since the last reply to this thread that they figured out their issue.

I always wonder what someone is doing when digging up way all threads. Why are you bringing up a 5 year old thread? I could sort of see asking a similar question, but you're answering one here...
