Rubber Membrane Diffusers are considered to be one of the most economical and low maintenance air diffusers available. The rubber membrane has many small holes which expand as air fills the membrane. Medium size bubbles are released. The rubber membrane does not clog like air stones. Little or no maintenance is required. Our Rubber Membrane Diffusers are designed to be very low back pressure so you also get the best performance from your Hakko air pump.
Our Matala Air Discs are 9 inch diameter and are designed for the wastewater treatment industry to very high standards. The air por size in the rubber membrane is designed to give a medium size bubble which will not put any significant back pressure on the system. In fact this special air disc only adds less than 6 inches of water depth back pressure. The 3/4" male thread makes it easy to attach to your feed line. Capable of handling air flows of 40lpm to 120 lpm. The disc is very low maintenance and in some cases NO maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning. We have some of these air discs in systems now for over 3 years with out trouble or maintenance.
Our Air Tube Diffusers are designed to be a drop in system. The rubber membrane is wrapped around a hollow PVC tube. It is negatively bouyant but you may also add small stones to the inner tube to increase weight so it stays put on the bottom of your pond or lake. 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.
To clean, simply wipe with a rag and clean water occasionally.
If you live in area with drastic temperature changes, be sure to build your pond deep. Deeper ponds will have more stable water temperatures. The temperature in shallow ponds can fluctuate radically in spring. These fluctuations can make it difficult for beneficial bacteria to colonize.
