Product description

Small World Aquarium Filters are specifically designed for small aquariums of all shapes and sizes up to 5 gallons. Quick and easy to install, Small World Aquarium Filters keep your water crystal clear while eliminating contaminants and maintaining a healthy environment for your fish. This filter includes a bracket measuring 4-1/2"x 1-1/2"x 1" and fits in almost any small aquarium with an easy to replace disposable cartridge filter. The high quality disposable cartridge consists of carbon and zeolite for chemical filtration combined with a bio foam sponge. The zeolite crystals eliminate ammonia while the top quality activated carbon removes harmful gases and odors. The bio foam helps promote biological filtration leaving you with crystal clear water. These filters attach easily to any air pump (not included) using your existing tubing and will help keep your small aquarium healthy and looking beautiful.
