iodide....necessary???

[mike90]

Do you a lot of you veteran reef holders add iodide to your tank? I've been reading about it for a bit and it says its mainly good for invertebraes and stuff like that. I have a 90 gallon with the basic clean up crew with hermits and snails. Should I be adding iodide or is it not that necessary? I was looking at this stuff.

Nope, I let water changes take care of that stuff. It's in the salt mix.

Iodide is toxic if there is too much, so be careful, it's something you really don't want to overdose.

Nope.

What is the percentage of a water change that will bring these levels back up :?:

Although Iodide is one of the elements that gets depleted the fastest, so dosing it in a heavily stocked tank may make some sense.

I do not do water changes often or regularly. So, I dose about 2ml. a week(one ml. every three to four days).

You might want to test your water to see if where your iodide level is before you start dosing.

I also believe it is in a lot of frozen fish foods and some is added when you feed the fish this way, could be wong though.

Unless the mix has more then the level you desire, 100%!!!!!

Water changes can not be used to maintain anything at a level equal to or above what is in the salt mix. If the levels in your tank drop to half of what you want, after a 50% water change you will only have 75% of the iodine you want. Even a 90% water change leaves you 5% below desired levels on day one, and they drop after that, especially with skimming and bioload.

If you need to maintain iodine at the levels in the salt mix you need to get it from somewhere else. That does not necessarily mean supliments since a calc reacter food etc can be adding it to your tank.

IMO it's important to remember that some trace elements can be present in artificial seawater mixes at concentrations many times that of NSW, so it's not unrealistic that a partial water change could provide a means of trace element supplementation.

IIRC, one of the fairly recent tests done on IO mix showed iodide levels at something like 9X the concentration found in NSW. So, in that case, approximately a single 11% water change can replenish your system's iodide concentrations from nothing right back to NSW levels.

i do have the luxuary of getting my water from the ocean, should i alternate from one to another. meaning making my own every now and then :?:

 

[mike90]

thanks for all the input guys. i think im going to start by getting an iodide test kit.

Since there's probably nothing in your tank that needs Iodine in the water why bother with getting a kit and dosing it?

My ecosystem take's care of that, it has all kinds of trace elements in it, i've never added it to my tank, my reef has been up going on ten years, even before i got my ecosystem i never added it.
