About This

• Perfectly sized for small to medium aquariums (up to 20 gallons), this filter is easy to install without extra tools. Works with air pumps (not included) for reliable filtration, suitable for beginners and experienced aquarists alike.
• The soft foam sponge creates a mild water circulation that won’t harm tiny fry, delicate shrimp, or slow-moving bettas. Prevents suction injuries and stress, making it ideal for breeding tanks or nano aquariums under 20 gallons.
• The porous sponge media cultivates beneficial nitrifying bacteria, which efficiently breaks down ammonia and nitrites—key to maintaining crystal-clear, healthy water. Reduces the need for frequent water changes and supports a stable aquatic ecosystem.
• Simply rinse the foam sponge with tank water (no harsh chemicals!) to remove debris—no complicated disassembly required. The durable foam material is reusable for long-term use, saving you money on replacement filters.
