I have a 45g Jbj which is 25.6"W x 15.5D x 18.5"T. I plan to have a mixed reef with very little sps some Lps and mostly mushrooms and zoas and possible a BTA. Do you think one radion xr15 would work? I know they say 24" × 24" coverage and BRS recommends 18" x 18". Looking for some real world experience and opinion.
