I'm about to purchase a UV
sterilizer for my tank. I plan to plumb it with my canister on the return side.
The canister is rated at ~280gph... most of the 9w UV
's I am looking at (CSL's Double Helix and the Cora Life Turbo Twist) are rated at 200gph max flow rate. Do I need to consider going with an 18w UV
I understand a UV
sterilizer is not effective if you exceed the max. flow rate so I want to make sure I get the proper size.
