What is the difference between an airstone diffuser and a rubber membrane diffuser?
The airstone diffuser and rubber membrane diffuser both help aerate your lake or pond. However, they do it differently and work better in different sizes of water. Airstone diffusers are easy to install and less expensive, but they produce less oxygen than rubber membrane diffusers, which have smaller bubbles and are more costly. Airstone diffusers work well in smaller ponds while rubber membrane diffusers are better for bigger ponds because they create more bubbles and oxygen throughout the water. However, some argue that the airstone diffuser also produces sufficient oxygen with its bigger bubbles that pop. Ultimately, choosing between the two depends on factors like price, maintenance frequency, and the size of your pond.
