I am looking to purchase a UV sterilizer because all the information online tells me that it will significantly boost the health of my fish. I have a 240 gallon tank with 70 gallon sump/fuge. In my fuge I have a SWC 250 Xtreme skimmer and in my fuge i have about 20lbs of live rock with macro growing in there. I have about 220 lbs of live rock total. Will a sterilizer work miracles? if so which one?
