Recently, an experienced hobbyist on this forum highly recommended the Submariner UV sterilizer. This filter combines the UV and biofilter into one apparatus. I just bought one ($80) and am going to set it up for my 50 gal tank. It has a 7 watt UV lamp. I'm going to use this tank as a quarantine tank for new fish.

Proper Aquarium Water Quality: UV Sterilizer Selection Guide
When using a UV Sterilizer in a home aquarium, the UV unit should be placed last in the filtration line. You want to first filter the aquarium water through your and then run the water through the UV device before returning the water to your fish tank. By first removing the solids in the aquarium water with your mechanical filter (canister filter, etc), you are helping your UV unit to attain maximum operational efficiency.UV Sterilizers have been in use for many years and has provided the owners with a level of confidence that the chances of fish contracting a parasite or disease are lessened to a great degree. This of course is based upon implementation, strength, and contact time (flow). The way it works is, water from the tank flows through a chamber around an ultra violet light source, and then flows back into the tank. The return water is “reduced” of the microorganisms that pass through it.For example, you might consider a lower water flow sterilizer if you own a fish tank and extra water flow sterilizer and UV light bulb power for your outside pond.Aquatic enthusiasts prefer this method of sterilization because it has no residual effects. Only the water which passes through the sterilizer is affected by the UV radiation. This will not affect any microorganisms living on the fish, rocks, or coral in the tank, only the water which circulates around them. This helps the aquatic environment as a whole build its own defenses, and makes for a more stable setup in the long run. As it is a method of sterilization and not specifically designed to kill microbes outright, its main action is to make microorganisms incapable of reproduction. This eliminates the worry about bacterial die-off overloading the tank. From this perspective, UV sterilization has no negative effects on the environment.
