Hydrus Sponge Filter

The Hydrus Sponge Filter is a quiet, efficient, and low-maintenance filtration system commonly used in small to medium-sized aquariums. This filter works through a combination of mechanical and biological filtration. The sponge acts as a physical filter, trapping debris, while also providing a surface for beneficial bacteria to grow, helping to break down harmful ammonia and nitrites in the water.

Typically powered by an air pump, the Hydrus Sponge Filter creates gentle water movement and aeration, making it ideal for aquariums with delicate fish, shrimp, or fry. The filter is easy to install, clean, and maintain, and it doesn’t disturb the tank's inhabitants with strong currents. Its simple design makes it a popular choice for aquariums, quarantine tanks, or breeding setups.
