Dead cleaner shrimp

[margaritaville]

Came home last night and found my cleaner shrimp dead. It is in a 20L with about 10 lbs of liverock a sixline wrasse and a damsel, 1 mushroom and about 5 crabs and 5 snails. All levels are good, nitrate is around 20. I did start adding (Kent) iodine, about two drops per day, in the past two weeks, could the addition of iodine caused the death? Any thoughts?, Im at a loss.
Thanks

Is it really dead or is it possible what you found was the outter shell that it shead during the molting phaze.

Eric:

Since you read my last link thought I would shoot you another. Really iodine is a complicated thing to dose and test as there are many different forms (iodide, iodate, iodine, etc.

Reef Aquarium Water Parameters by Randy Holmes-Farley - Reefkeeping.com hope this helps, but I would just stick to water changes for your iodine.

Just my .02.

BTW sorry about the loss of your shrimp. I suspected something similiar when I dosed lugol's iodine to heavily in my tank in the past before, but could never say for sure.

I now only dose alk and calcium and do my waterchanges for everything else.

No its dead.
Thanks for the link and info bk. Ive heard salt pretty much has everything you need and waterchanges replenish the system. I do a 5 gal waterchange every week on my 55 reef.
Also I do about a 10 gal change weekly on my 75 predator tank. Think this is safe or overkill?
Thanks again

If you do regular water changes you will be fine. The only things I manually adjust are calcium, alkalinity and magnesium(rarely).

FYI I do a 20 gallon water change every other week on my 100 gallon.

Hope this helps.
