It seems that my Iodine level is .02-.03. I guess .06 is what I need to strive for... Each week , I add a capful of Kent Iodine as suggested on the bottle. Evidently, I'm losing it in the skimmer. Is there a "safe" way to increase the Iodine level? Also , I'm losing some yellow polyps-- noticed shortly after placing a brown brittle star in the tank. I haven't observed the star at night eating anything other than scouring the floor of the tank. Any suggestions?
