I have a 90 gal reef tank, I used RO/DI water made up days prior to using. I have a 20 gal sump using a ETS downdraft skimmer, and a calcuim reactor. My problem is if I don't put a declorinator in daily, my fish die and the corals close up. I have reverted to using a declorinator drip to keep things alive. I have rinsed all the live rock and even removed the substrate. I add no additives but Iodine. Can anybody help me
