WebMay 3, 2024 · Stick diffusers: Have smaller surface area, but typically put less pressure on the aeration system and are better for pond mixing. Membrane stick: Usually fine bubble and made from EPDM rubber with the same characteristics as the disc version. There are some medium pore membrane diffusers. Ceramic stone: Usually fine bubble with the same ... WebGravity aerators are simple to construct and are reliable. These are the most common type of aerators used in small semi-intensive shrimp farms. In this method water is allowed to rise above, the pond/tank level and then to fall freely in the pond or tank through atmosphere, where water comes in contact with oxygen and thus aeration is done.
