Collection: Aquatop UV

Two Aquatop items appear on this page: the SPNano-UV submersible aquarium filter and the 5 watt bulb that replaces its lamp. Being submersible, the unit works inside the aquarium rather than being plumbed into a return line, with the UV lamp housed alongside the filtration in one body. The bulb is the part that wears out in that arrangement, and it is sold separately so that a lamp reaching the end of its life does not call for a new filter. Confirm the wattage against the unit first, since the bulb listed here is the 5 watt.
