i am setting up my tank and doing the plumbing. i ahve got a uv
unit from by old planted discus tank, and was thinking of using it on my new reef tank, but then i have heard that you shouldnt use them on reef tanks, its okay on fish only, but on reef tanks that they are supposed to kill some of the beneficial bacteria in the water so you dont need one and shouldnt use one.
so i was wondering what you guys thought of this and whether you use one or have used one?
all help very much appreciated,
