Boyu DGN-80 / 120 UVC Canister Filter
A newer, white-bodied canister with a UVC lamp built in and a one-button prime. It comes in two sizes, each offered with or without the A suffix. Handy if green water has been a recurring headache, though a planted tank with good balance rarely needs UV running all the time.

Frequently asked questions
Quick answers about the Boyu DGN-80 / 120 UVC Canister Filter, drawn from its specs.
What size tank is the Boyu DGN-80 / 120 UVC Canister Filter good for?
