Tetra Whisper 10-30 Gallon Internal Power Filter for Aquariums

These 10-30 tetra internal filters are unusually quiet since the motor's under the water. Offering the same quality and performance as an external filter, it'll function in as little as 2" of water, allowing it to be used for turtle tanks or for creating a waterfall inside the tank. This Tetra whisper filter uses tetra's bio foam, which eliminates toxic ammonia and nitrates that are not healthy for fish. Designed for aquariums up to 30 gals, it's easy to adjust in high or low water levels with mounting suction cups and/or brackets. Each 30 gal fish tank filter comes with one whisper filter cartridge. This way, you can get regular reminders to clean and maintain it, simplifying the care process.
