I'm looking into getting a UV sterilizer for my 65 gallon tank. I'll be hooking the inlet of the sterilizer to the discharge of the return pump, then hooking the discharge of the sterilizer to the pipe that goes back to the display tank. For my tank (reefer 250) the recommended flow rate is 660GPH, so that's a flow rate I like to maintain.
I'm thinking all I need is a 15W or 18W sterilizer should be plenty. But their flow rates are around the 200GPH to 250GPH. The only way I can achieve a 660GPH flow rate is if I get something ridiculous like 40W. Do I really need to buy a 40W? Or can I get away with a 18W and go higher then their recommend flow rate?
