Thank you for choosing Aquatop’s SPNANO-UV submersible UV sterilizing lter. This innovative and exible design
is perfect to help you eliminate unsightly algae and control unwanted algae blooms. The UV bulb aids in the health of
aquatic life by eradicating free oating microorganisms and disease causing pathogens in both salt and freshwater
aquariums.
The SPNANO-UV Filter uses a submersible top-mounted pump to draw water past its compact UV bulb. The UV bulb
is encapsulated in a unique quartz tube and includes a sponge pre-lter to mechanically lter organic waste before
water passes over the UV bulb.
The versatile design of the SPNANO-UV Series Filter allows for UV Sterilization to be submersed in both fresh and
saltwater nano aquariums. With its compact size, the SPNANO-UV can be easily mounted vertically or horizontally in
smaller aquariums or sumps tanks. The design allows for easy installation and maintenance.
Please reference this manual for any questions and/or instructions for use. May Aquatop’s SPNANO-UV submersible
UV sterilizing lter serve you and your aquatic creatures well.
