Why Should I Aerate My Pond?
Aeration increases oxygen levels, which not only benefits fish and plants but promotes beneficial bacteria growth in biological filters, Aeration also lowers toxic gases and ammonia by promoting gas exchange, reducing chance of winter fish kills by keeping a hold open on the water's surface. Aeration can also be used to agitate stagnant areas of the pond, drawing debris into a skimmer or bottom drain.

Mounting Instructions
The Matala high volume air pumps do not come with the air outlet threaded inside. This is because the manufacturer does not want users to restrict the air flow. Instead, the large 1/2" O.D. outlet comes with a rubber elbow that is 1/2" I.D on one end and 5/8" I.D. on the other end. We encourage using this elbow to adapt to PVC, flexible PVC or to a gang valve like the Matala Hakko Heavy Duty Brass Gang Valves.
PGP Tip
We recommend using a gang valve and keeping an extra valve open. During setup, use this extra valve to "bleed off" excess air so that there is not excessive back pressure. Slowly close the extra valve until the air flow is at its maximum. Do not continue to close valve beyond maximum airflow, as this excessive back pressure will shorten the life of your air pump diaphragms.
