Aquarium Sponge Filter with Biological Filtration

Quiet, Effective Filtration for Clear, Healthy Aquariums

This sponge filter provides reliable mechanical and biological filtration to help keep your aquarium water clear and stable. Made from durable sponge and sturdy plastic components, it connects easily to a standard air pump to circulate water through the foam, trapping debris while supporting beneficial bacteria growth.

Measuring approximately 12 x 5 cm (with tube), this compact filter is suitable for tanks up to 80 cm in length. It is especially well-suited for betta tanks, fry rearing setups, and shrimp aquariums where gentle, low-flow filtration is essential. The sponge structure offers a large surface area for nitrifying bacteria, helping to maintain a healthy nitrogen cycle while improving oxygen transfer in the water column. When connected to an air pump, it also helps reduce pump noise by diffusing air output through the sponge.

Why It's a Smart Choice

• Dual filtration action - Provides mechanical filtration to capture fine particles and biological filtration to support beneficial bacteria.
• Safe for delicate species - Gentle water flow makes it ideal for bettas, shrimp, and fry that can be stressed or harmed by stronger filters.
• Easy to install and maintain - Simple connection to an air pump and straightforward sponge rinsing for regular cleaning.
