Keeping your small fish tank clean and healthy has never been easier with our 4-piece mini aquarium sponge filter kit. Designed specifically for tanks up to 5 gallons, these compact filters provide powerful biological filtration without the noise and complexity of traditional filter systems.
Each filter features high-density porous sponges that trap harmful microorganisms, uneaten food, and fine particles that can cloud your water and harm your fish. The unique sponge and gravel combination creates the perfect environment for beneficial bacteria to thrive, naturally breaking down ammonia and nitrites while increasing oxygen concentration in your tank.
Unlike noisy electric filters, these air-driven filters operate completely silently, making them perfect for bedrooms, offices, or any space where quiet is important. They work by drawing air through the filter, creating gentle water circulation that keeps your fish happy and comfortable without disturbing your peace and quiet.
Setting up your mini filter couldn't be simpler - just attach it to your air pump tubing and you're ready to go. Cleaning is just as easy - simply remove the sponge, rinse it in your tank water (never tap water!), and gently squeeze out the debris. Monthly maintenance keeps your filter performing at its best.
This 4-piece kit is perfect for various small aquarium setups including betta tanks, fry tanks, shrimp habitats, and quarantine tanks. The compact size (80mm height, 50mm diameter) ensures they fit discreetly in any nano aquarium setup without taking up valuable swimming space.
Whether you're new to fish keeping or looking for an additional filtration solution for your existing setup, this sponge filter kit provides reliable, low-maintenance water purification that keeps your aquatic pets healthy and your tank looking its best.
