iodine dosage

[Marinesavy]

Can anybody enlighten me the impact of overdose iodine ?

Currently i am running a 24g nano cube, I have been keeping corals for months and all seem fine. I am thinking of getting seachem iodine to add as a supplement for my corals. I do water change 5 - 10% weekly and trace elements shouldn't be a issue.

Iodine is my concern, which brand and underdose is way better than overdose right ?

overdose can be fatal to inverts.... so it is always safer to use testkit to check....

but alot of pple who keep to the routine of just wkly water change has stable results which really dun need to put additional.... only in cases that u need to 'heal' a coral / invert.

Thanks nicholas, I stick to water change weekly and so far... everythings were fine as of today.

I do understand that salt mix have trace elements like calcium, strontium etc.

but it doesn't have iodine in it, heard that iodine do make corals colors nicer, that why i thought of putting iodine as a supplement, guess after hearing your advise, i might not get iodine anymore.

i have come to realise that overdosing of iodine will cause lose of coraline algae....correct me if im wrong....

Hi Alvin

I am not sure about that. I only know that low magnesium will have problem maintaining calcium and thus coraline algae.

Marinesavy: I still keep a bottle of iodine to use very sparely on few occassion. It is so far that I didn't really dose it regularly or even do not dose at all.

Nicholas.. since you don't dose regularly, but you do sometimes, do you see improvement on your corals ?

Iodine is less critical for coral, dose less and spit to two does for safer diffusion. If you dose 1 capful per week, you may spit to 1/2 capful twice a week. Thus the LS/coral will not react so much to it.

Test Kit I find waste of money since it is good for the first test. After that no use liao, as I will stick to the confirmed dose.

Thanks, i may get it and try not to overdose it and see the result.
