I tested iodide and had a reading 0.02-0.03ppm, now it is 0.2ppm. How do I get the iodide level down?

Activated carbon will take it out of the water

Changing water sure won't hurt and will help to dilute the Iodine.  I saw your post on Reeffrontiers and because of the sudden appearance of excess Iodine, I would really suspect the test kit.  Does your kit have a standard to validate reading against?

I have a Salifert kit and possibly a SeaChem kit you are welcome to use for comparison.

My personal experience with excess Iodine is that it will only cause a problem with the shrimp & crabs by making them molt excessively.  Iodine will also slowly dissapear in the tank over time.  It didn't sound like you added any Iodine, so if it is truely there, I would be more concerned as to where it came from.  I certainly would test a new batch of saltwater.  

For what it is worth, several years ago there was a lot of debate as to the best salt on the market.  Several people who are professors at Universities did full bio-analyisis of the different salt mixes and found that Instant Ocean was the most consistant (between batches) and more closely replicated true ocean water than any other mix.  Also if you print the Internet price from PetsMart and take it into the Store, you can buy 150 gal bucket for $31.00.

I should be home this afternoon (after 3pm) if you want to test your water.

Rick, I am playing volleyball this noon. Maybe I can bring water to test over tonight  or some night this week. Phil will call before we come over.
