The PetWorx Aquarium Sponge Filter is the perfect low-flow filtration solution for nano aquariums, fry tanks, shrimp setups and betta tanks. Designed to provide gentle mechanical and biological filtration, this compact sponge filter helps maintain crystal clear water while protecting delicate fish and shrimp from strong currents.
The fine sponge structure traps debris and uneaten food, while also creating a large surface area for beneficial bacteria to grow — naturally breaking down harmful ammonia and nitrites to keep your aquarium healthy and stable.
