Hobby Mini-Long air diffusers and Hobby Long-Long air diffusers are suitable for all air pumps. Both air diffusers, Hobby Mini-Long and Hobby Long-Long, release fine air bubbles into the aquarium water. These air beads biologically clean the water of the smallest impurities and ensure that your aquarium and the water become crystal clear again. You can easily connect several Mini-Longs or Long-Longs together to increase the effect even more. The diffusers are available in two sizes: Mini-Long (3x12.5cm) and Long-Long (3x25cm).
