#ed_op#DIV#ed_cl#I am going to buy a UV sterilizer-- any suggestions? I heard higher wattage kills parasites? I think I have parasites in my tank b/c I have recently experienced about 4 unexplained fish deaths in my tank. I saw one that has "ozone" in it? Is that beneficial? I have a 55 gallon reef tank-- Are hang on or in-line better? I currently have a canister filter but I want to switch over to a wet/dry-- will I be able to use my UV sterilizer while changing over to a wet/dry? Will bacteria be able to grow in the wet/dry with a UV sterilizer present? Looking foward to your recommendations--#ed_op#/DIV#ed_cl#
