Air Pump Diffusers and Accessories
Air pumps will require separate components to operate - tubing, manifolds, diffusers, etc. Whether you need accessories or replacement parts, we have what you need.

Matala Air Disc Diffusers are available in 3", 7", 9" and 12" diameter sizes. Made of high quality EPDM rubber for use in water gardens, aquaculture and waste water treatment industries. Precision perforated I-shaped slits open when airflow is present and close when airflow is stopped, which increases durability and longevity, as well as cleanliness. These diffusers offer the lowest back pressure in the market.
MD-3W and MD-7W have weighted bases. MDB11 and MDB22 features a hollow base that can be filled with sand or gravel.
These discs are very low maintenance and in some cases no maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning.

Matala Hakko Air Tube Diffusers are designed to be a drop-in system. The rubber membrane is wrapped around a hollow PVC tube. The air holes are a little larger than other brands, so you get medium-sized bubbles which do not clog and put very little back-pressure on your system. This means very low maintenance and effective aeration system.
Can be filled with rocks or gravel
in order to be weighted down.

Quick Sink, self weighted membrane air diffuser assemblies are designed to be placed at the bottom of a pond or lake. The self weighted design eliminates the need for gravel and reduces installation time. The Quick Sink diffuser assembly features round rubber (EPDM) membrane diffusers with thousands of holes which produce small air bubbles when supplied with air from an on shore compressor. These bubbles rise to the surface and create circulation that helps destratify and aerate the water body.
