The Air Tube Diffusers are manufactured by Matala and gives you low maintenance and an effective aeration system.
The two different tube diffusers we offer from Matala are the non-weighted and weighted diffuser products. Both of the tubes are made of recycled rubber. They also have super fine pores to create a large mass of bubbles.
For the Non-Weighted Tube Diffuser (MTD-300 and MTD-600) you must add small stones to the inner tube to increase the weight so it stays at the bottom of your pond or lake. A plug is included to prevent the stones from falling out.
The Self-Weighted Tube Diffusers (MTD-300W and MTD-600W) are self weighted and come with 2 types of barb connector, which must be glued in place. These are designed with a hose barb and self weighted air hose allowing the diffuser to sink to the bottom.
