Why would a UV
effect a fuge?
Fuge removes excess nutirents.... UV
kill free floating algae and critters that are unlucky enough to go through the light so you may kill off a few pods
. If you use a UV
you need to have the water flow very low through the light so running on the return line is not a good option. Dwell time is what kill the items so you need low flow through the light. I had one on my 125 reef for over a year till the RIO pump crapped out and my UV
backed the inside and released a PVC
power into the tank causing a LARGE headache and killing some corals and a fish. Tank was fine and the fuge until then... Why do u think you need one? Piece of mind? thats why I had mine and it messed with my mind...
