Betta Sponge Filter for Aquariums with Slow Current

<ul><li>Replace Traditional HOB & Canister Filters for Cost-Effective Performance</li><li>Specially Designed for Betta Fry & Small Aquatic Pets</li><li>Provide Supplemental Food for Fry with Nominal Current</li><li>Perfect for Up to 10.5 Gallon Tanks When Used Singly</li><li>Easy to Wash & Reuse for Long-Term Use</li></ul>

Brand

This Biochemical Sponge Betta Filter is specially designed for aquariums housing Betta fish, fry, and other small aquatic pets. Unlike traditional Hang-On-Back (HOB) or canister filters, our sponge filter offers an economical and efficient alternative without frequent cartridge replacements. With its gentle, slow water current, it ensures Betta fish, fry, goldfish, Discus, Dwarf Cichlids, Guppies, and Krill fish can thrive comfortably without getting trapped or stressed. The minor bubbles generated by the sponge provide a nominal current, which promotes healthy breeding and spawning while also aiding in the distribution of supplementary food. This filter works perfectly in aquariums up to 10.5 gallons when used individually. Simply connect it to an air pump (sold separately) via airline tubing to create oxygen-rich, aerated water. Note that the base of the filter is not weighted, so you may need to secure it with a small object. For maintenance, rinse the filter in tank water during water changes to preserve beneficial bacteria. Its reusable design ensures long-term cost savings and eco-friendly usage.
