UV, sel., FW

I have a125 gallon with discus. What size uv sterilizer would I need to
use.
Thanks!
<Will depend on the brand. You'll find each one rated for
aquaria up to a certain size. What's acceptable for a marine
aquarium will be acceptable for a freshwater aquarium as well. Will
also depend on how it is connected to your aquarium (i.e., the flow
rate of the pump used). Do remember that UV sterilisers reduce the
risks of problems such as diatom blooms and Ick outbreaks: they do not
entirely prevent them. For the most part, quarantining is a much better
approach, and there's little value to UV sterilisers so far as most
freshwater aquaria are concerned. They're most cost effective when
used with ponds and to a lesser degree marine aquaria.
Cheers, Neale.>
