small, lightweight, connects to return pump, and is hidden out of sight in the hidden compartment behind the back wall of the biocube.
I just recently had my mini V2 UV sterilizer connected to my return pump in my aquarium. It is doing a tremendous job of getting rid of the bad bacteria and the free floating algae in my 32 gal. corallife biocube tank, and the water in my tank is crystal clear. I would highly recommend this product if anyone is experiecing nuissance algae and bad bacteria in their aquarium water, and also if their filter is not keeping the water crystal clear.
