I also tried one bucket of sea chem and changed back to reef crystals within a few weeks as I thought the stuff was terrible. I'll never use it again. FYI, I have dosed iodine for years as well. Something else you may want to try is iron, is helps the greens stay brighter. Like Chin said and I eluded to earlier, carbon isn't very selective about what it will absorb so you need to replenish some of the elements from time to time.
