Silica Airstone Diffusers 1-1/2" x 1/2" x 1/2" 1 pk
Excellent air defusers
These defusers provide plenty of bubbles from the air supply to keep the water open. I have a 5.8 CFM aerator now running only 6 lines of the 14 available and the water is open with a 3 foot diameter when the temp is in the teens.

Sturdy and plenty od bubbles
To begin with, I bought 3 large ones just to give them a try. Since I have bought 12 more and them on all my aerators in my ponds. They blow great bubbles, are easy to attach & unattach to airline tubing and easy to clean when I am refilling with water.

Worked perfectly in our small backyard pond.
I purchased this air stone to give a fish some extra oxygen. We have a waterfall but the extreme heat and humidity reduced the amount of oxygen required by the older bigger fish we had. Our older fish perished. If we had purchased the air stone and air pump sooner we could have saved them.

This product has a nice design.
I have bought, and found that these aerators work great in my pond. With a long design they provide a wide plume of air into the water at a very good rate, that is needed. With it's large pores it will not clog up for a very long time, which is important so I don't need to replace them often. Also, they have an excellent price for this product making them a bargin for what I use them for.
I would surely suggest to anyone looking for a product like these. to be very satisfied with thier purchase as I have. I have tried smaller versions that just didn't work out as well in the application that I put them in. I'm using these with a Little Giant pump which has plenty of air supply to provide maximum airtration for my pond throughout the winter.
