The River Tank requires very little maintenance due to its ecologically balanced design. Its continuously flowing water provides an oxygen-rich environment for aquatic organisms, whose waste products provide nutrients for terrestrial plants. Molded plant pockets hold the plants in place and also make an ideal home for fish, snails, and shrimp. Ecosystem ships with an Ecosystem Mold already mounted inside the aquarium and includes a submersible pump, fully adjustable LED hood light, filter cartridge, and instructions. Measures 24 × 12 × 16" H.
To convert an existing 20-gal aquarium into a River Tank, purchase separately the 20-gal Ecosystem Mold Only (item #161538) and Aquarium Sealer (item #671972).
Note: We recommend that you receive and set up your tank several days prior to delivery of live plants or animals. River Tank Ecosystems do not include plants, animals, or gravel. See the River Tank Plant Set (item #161541), River Tank Animal Set (item #161545), and River Tank Accessory Set (item #161549).
