Interesting, that iodine will kill the bacteria we need, I guess thats why we are constantly adding it to the tank. Though we need proper iodine for molting and uv protection of our inhabitants.
I usually replenish my iodine through a water change but I found a great video where a guy with a 300 gallon was saying to do less water changes to create a more stable system. Constant water changes can unbalance the tank once it starts to settle out we change the water again and the cylce repeats. I am testing this theory out now myself to see. I will probably start with a month lapse and see what happens.
