JBJ Submariner UV Sterilizer (9 watt)

Keep your aquarium tank free of disease
The Submariner is the proactive solution for eradicating harmful micro-organisms and unattractive green free-floating algae in fresh & saltwater aquariums. This revolutionary UV sterilizer/clarifier is completely submersible, which can be placed either in the main body of the aquarium or positioned horizontally in a sump for a clutter free set-up. This utilizes a UV-C compact fluorescent lamp that is encapsulated in our unique Quartz Sleeve that is air tight and allows for a 99% transmission rate to efficiently neutralize disease causing pathogens. All models include an integrated pump with an adjustable swivel spout and large mechanical prefilter sponge.
