Product Details
These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfying applications. Unlike cheap air stones, these diffusers are easy to clean. EPDM membrane cleans much better and easier than the porous air stones. These diffusers are an excellent choice for pond and water garden aeration since they actually produce more circulation and water movement. Barbed inlets have multiple size barbs. Simply cut to fit the size tubing you are using.
In testing; these air diffusers produce a slightly larger air bubble than the air stones, which translates into less oxygen transfer into the water. So for fish holding tanks, raceways, fish productions ponds, etc. we recommend using alumina air stones.

Works well as long as you have enough air going through it. I use a pump that puts out 1700 cubic inches/minute. It's model AP-20 Supreme-Hydroponics by Danner Manufacturing, which is very quiet by the way. Anything less than 1000 cu in/min would not be advisable in my opinion. The air bubbles are larger than I expected, but with 1700 cu in/min it works just fine. I use it for making compost tea, 100 gallons at a time. My only complaint is that air escapes more from the ends, so the bubbles are larger than from the body. I expected the air bubbles to be uniform throughout. It doesn't seem to be a manufacturing defect, but just a way that it's made. I would prefer to use a silica stone if I had to do it over again to get the smaller bubbles, but I chose this one since it is easier to clean and will probably last longer.
