When I first started in the Saltwater hobby I started with a lot of Zoo's. They looked so colourful. I was amazed. I read that they like Iodine so I went out and purchased a bottle of Kent Iodine. I dosed at the level shown on the bottle. Before long the Zoo's started to disappear. I had overdoes the Iodine.

I am not sure if your dosing of Iodine is causing the problem, however you are adding a lot of Iodine. If you read the make up of all the items you are dosing, they all have Iodine in their make up. I would cut back on the dosing and the Iodine for sure.
