Hello! So I'm looking to get a UV sterilizer for my 80 gallon bow. I'm running two Eheim Ecco 2234 canister filters. I know absolutely nothing about UV sterilizers so any advice would be welcome. What is the best brand? And, how are they installed? I did some research but I'm still somewhat confused. I'm not really concerned about cost. Ease of use is more important to me. Thanks!
