Submersible UV filter with integrated UV sterilization. This innovative and flexible design is perfect to help you eliminate unsightly algae and control unwanted algae blooms.

U V steilizer

I got this for my 40 gal goldfish tank it worked great

This little guy packs a wallup!

I was surprised when this 5 watt unit completely cleared my 300 gallon koi tank full of "pea soup" heavy algae. In just a few days the water was clear to the bottom of the tank and more importantly I could enjoy watching my colorful koi again! I have an unboxing video of this unit and follow-up underwater koi video on the River Life YouTube channel. Thanks Team Aquarium Co-Op for coming through again with this highly efficient unit.

I received a UV filter and the glass was broken in shipment. I called Aquarium Co Ops and they sent me a replacement that arrived in excellent shape. Thanks Cory and his team. Excellent customer service. My 55 gallon turned from green to clear in a few days.

Excellent product

Does a terrific job cleaning water. Wish the pump part was available separately, as burned out two units pumps because of low water. The light continues to work well in these units. Filters require daily cleaning in my goldfish tanks, so does better in my sumps. I also have two of the larger models of the same UV filter (not carried by Aquarium Co-op).

great product
