Future UV Setup questions: I have a 125 gallon in cycle mode right now, but thinking about running UV Stage two (UV-2) in the future. I’m liking the Vectron-6 V2 600 25 Watt – Looks like the min. flow rate for UV-2 is 50 to 75 gph. www.americanaquariumproducts.com/TMCUVSterilizer.htmlBut in the same paragraph it says maximum effectiveness is 30 gph? It would overheat at that rate, right? Is that right? Confused? Max effectiveness is below the minimum flow rate. Any way… So what is the optimum flow to max rate for the Vectron-6 to achieve UV-2 sterilization? If so, what Rio power head will work? I’m looking at the Rio200 and the Rio 90. I’ll also add-on the Filter-Max I to help keep the UV unit clean. Or should I get a bigger pre-filter? Thanks! BrianB

In other words maximum effectiveness for level one Sterilization is 30 gph per watt, so in other words 625 gph, well above the minimum of 50-75 gph Level two sterilization for this UV is 12 gph PER WATT or 300 gph, with a turnover of 2-3 times per hour, assuming pre-filtration and some other key points Not sure your tank size, so I cannot comment on turn over, but the Rio 600 at even zero head pressure is only 200 gph, so this would not be a correct pump. Likely the Rio 1100 is the better choice References: www.americanaquariumproducts.com/AquariumUVSterilization.html#flowtablewww.americanaquariumproducts.com/RioPlusPumps.htmlCarl

Thanks again Carl!
"30 gph per watt, so in other words 625 gph" Wow!! The size of the tank is 125 gallons.
Thanks for clearing that up! I got it now!
