Tetra® ReptoFilter® for frogs, newts and turtle terrariums is the only terrarium filter you'll need. With efficient, three-stage filtration, Tetra ReptoFilter promotes clean, clear water in as little as 2 inches of water, making it ideal for the low-level aquatic environments small aquatic animals prefer. This small filter is easy to conceal behind a plant or other decorative object, and its lid keeps reptiles out. It removes debris, discoloration, odors and ammonia from terrariums. Tetra ReptoFilter is easy to set up – simply attach the suction cups and insert the cartridge – and simple to clean. Replace the filter cartridge every four weeks. You can even create a waterfall by camouflaging the ReptoFilter with rocks. This UL Listed product features a 2-year limited warranty – see product label for details.
