Product Overview

Viagrow Air Stones work with an air pump to create scores of tiny bubbles, adding much-needed oxygen to the water in aquariums, hydroponic and aquaponic growing systems. The larger surface area of the air stone allows for the production of a greater number of these bubbles, therefore increasing the surface area of the oxygen available to your fish or plants. As the bubbles aerate the water, they also help circulate hydroponic nutrients, invigorating the roots of plants and boosting healthy growth.

I tried to use this on my existing air pump on my 125 gallon aquarium but it was not strong enough to make this stone work. I will obviously need to buy a much bigger air pump to handle this size. The disc is really well made. Its nice and heavy, so I will not have to glue it to a rock to keep it submerged like the one I use now. It seems like it would last a long time because it is really SOLID in structure. I use this style now, only half its size, (I have two) and have used them consistently for the last 4 years without any problems. They don't clog, or fall apart over time and I LOVE the way they distribute the bubbles. My 10 inch goldfish has fun swimming threw the air stream. It must tickle. HAHAH
