I have a 5W UV Clarifier I'm going to use on my 55G setup.. I was reading that its good for upto 100G's.. Will this is my reef tank so I was told by a few people it will kill all the bacteria in my tank even the good stuff.. Shouls I put it running into my main tank or into the sump? Is this going to kill my pods?? How long should I run it a day?? BTW I have 2 tangs and 1 is showing sighs of Ick so this is why I'm going to set it up..
