Cougra reminded me of something else. If I keep my hands in the tank water for more than a few minutes, my hands start to burn. It's REALLY bad if I touch the anemones. My hands burn for hours. It feels like I'm getting electrical shocks. In fact, one day after handling the tank (changing water) I felt shocks but figured it was just the allergy. It turned out my skimmer pump was cracked and zapping through the water. I kept putting my hands into the water like a moron. Eventually I thought to myself, "Wow, this hurts more than normal. I think something is wrong."
