Hope everyone is enjoying the holiday. I’ve been researching a small UV sterilizer I could put into the over flow chamber , found one cheap on Amazon. Don’t care about blub replacement. Just want it to help with parasites. Recently got a bug from a blue tang the size of a quarter lost all my fish and guess what the blue tang lives and is healthy when it looked the worst ick plus black spotts everywhere . Feeding him green and purple seaweed that fish don’t mind the color lol. Healthy as can be . But took out 2 designer paired clowns , wrasse , and my most favorite bi-color blenny . This Tang was purchased at the local fish store they so call said they had it acclimated in copper before display tank . Back in Miami Florida I never had an issue similar to this . Guess we can say I am trying to do preventative maintenance, any how what are your thoughts on this 11w UV it’s 10” and will be connected to a pump real soon. My AIO is a 40 gallon long .
