Following the same quality that you know from our award winning fountains, our SA line of aeration systems will keep your pond and lake healthy at a reasonable price. We have designed our aeration systems from the best materials. All parts are manufactured to our own specifications. The final product is an efficient, effective system.
Our HD manifolds provide features you will not find elsewhere: pressure gauge options, mounting tabs, extra wide air-flow cavity, etc...
Multiple air diffuser options are available to allow you to fine tune your system to how you want it to perform.
Our weighted air hose is thick, tough, and designed to hook right up to our manifolds and pumps.
If you are not sure what size pump or which type of diffuser to choose, check the FAQ section.

What pump do I choose?
The FLF-SA100 is the smallest pump in our SA lineup and is suitable for 1-3 diffusers and up to 65 feet of air hose.
The FLF-SA150 is the medium model pump. It can handle 1-5 diffusers and up to 100 feet of air hose.
The FLF-SA200 is the strongest pump in the SA series. It can handle 1-6+ diffusers and up to 175+ feet of air hose.
What type of diffuser do I need?
This is a matter of preference. Glass diffusers produce a finer and smaller bubble. This leads to more aeration.
Rubber membrane diffusers are cheaper and easier to clean. They produce a slightly larger bubble than a glass diffuser.
Our HD Glass diffusers are self weighted as are the single and dual 'Self Weighted Membrane Diffusers.
Although not technically self weighed, the HD rubber diffusers (6", 8", 12") will stay on the pond or lake bottom when used with our standard weighted air hose.
Regardless of the type, the longer/larger the diffuser, the more aeration is will provide.
How deep can I put a diffuser?
The optimal depth is 1 to 10 feet. The deeper the diffuser, the more resistance there is to pump air to that depth. Review the specifications tab to ensure that you are not under powering or overloading your aeration pump.
Can I buy a larger manifold than I need so that I can add more diffusers at a later time?
Yes- you can close the output valves on our manifolds on the ports you do not need to use.
Do I need a gauge on my manifold?
Although not mandatory, we recommend this as it will help you monitor system pressure and identify issues such as air leaks or dirty diffusers. Too much pressure can damage the pump.
Can I use this to prevent my pond or lake from freezing?
Yes! Many of our customers use our aeration systems to keep areas of their ponds or lakes from freezing- especially if they want to leave their docks in year round.
Are your pumps weatherproof?
Yes, our SA series aeration pumps are weatherproof and have an IP44 rating. We do recommend to try to protect the pump from direct sun in very warm climates if possible.
Can your pumps be rebuilt?
Yes- Our SA series pumps can be easily rebuilt should the diaphragms need to be replaced. We have the necessary parts available in the parts section of our store. We also offer a mail-in service should you not want to do it yourself. Call us for more info.
Works great for my bioreactor filter. Strong air flow!
Bought the SA150 Aeration System to aerate in the Summer and keep the area by our dock from freezing during the Winters here in the Northeast. It's worked great. We run in 24 hours a day and the quality of the water is much better than before. Algae is reduced and best of all, no dock removal in the winter!
