At Joe's Aquatic World we offer a wide selection of undergravel filters for marine aquariums.
Our range of undergravel filters are an excellent way of keeping the water in your marine aquarium crystal clear and healthy.
Undergravel filtration works by drawing water through the gravel in your tank that possesses purifying bacteria colonies, which subsequently works as a mechanical trap for the bacteria to purify any harmful nitrites.
