Clorine or iodine buildup

[birdman3782]

I posted a problem I thought might be a clorine buildup. I was then told it could be a iodine overdose. If this is true what could be the oxidizer in the tank? I have a ground probe on the tank. If I don't still use a declorinator the fish die and the corals start closing up.

I do a big water change man ! Have you been dosing your tank with Iodine? The oxidezer could just be atmospheric o2 I know that my d.o. levels run pretty high but, I have a lot of water movement. If you haven't been useing an iodine supplement I really don't see how that could be it. Have you called you local water departments latest breakdown on particulates etc in your water? If you could tell us a bit more it would really help to solve your problem.

I have city water but use a RO/DI maxima II unit. I have a ETS protein skimmer, ehiem calciun reator, not substrate and 100 lbs of live rock. Iodine is my only additive. If I don't use a declorinator drip all starts dieing

You've stopped adding the Iodie I assume. I'd do a big water change like 50% and next week I'd change another 50%. That should remove most of the excess iodine. I wouldn't add Iodine to the tank unless you have something that depletes it like lots of soft corald for example. There is probably enough trace iodie in your foods to meet your need under most tank conditions.

clorine or iodine

Thanks for the info. I have stopped the iodine. I have nothing but soft corals in the tank. Could excessive Iodine cause the same indications as clorine? When I add the declorinator all is fine.

Thanks

Yes it could. I wouldn't add it or anything elseunless I was testing for it. Unless you've got a bunch of them feeding should supply most if not all of the trace elements you need or it has for me anyway. I don't have a ton of softies yet but, I'm working on it.
