Air Tube Diffusers
These Air Tube Diffusers are manufactured by Matala. They are designed to be a drop in system. The rubber membrane is wrapped around a hollow PVC tube. The air holes in our tubes are a little larger than other brands so you get a medium size bubble which does not clog and puts very little back pressure on your system. This gives you a very low maintenance and effective aeration system.
The Non-Weighted Tube Diffuser (MTD-300 and MTD-600) must add small stones to the inner tube to increase the weight so it stays put on the bottom of your pond or lake. A plug is included to prevent the stones from falling out. These Tube Diffusers are approximately 2.6 inch diameter. The inlet connector is a a multi-barb adapter with 4 sizes of barb. 3/8",1/2",5/8" and 1" sizes.
The Self-Weighted Tube Diffusers (MTD-300W and MTD-600W) are self weighted and are approximately 2 inch diameter. These come with 2 types of barb connector which must be glued in place. Use standard PVC glue. One barb size has a 2 barbs, a 5/16" barb or 3/8" barb. The other barb is a 1/2" barb size.
To clean the rubber membrane, simply wipe with a rag and clean water occasionally.
