I am adding a turbo twist 18 watt uv sterilizer to my 90 gal tank (20 gal sump). I am using a maxi-jet 600 (160 gph) to push water through it. It has the option to be a venturi pump, but should I make it as such to send it through a uv sterilizer, or just let it push water with no bubbles? Thanks in advance for your help!
