Secret To Pond Excellence

Kasco Robust-Aire Pond Aeration System is one of the most efficient diffusers available on the market right now. It was carefully designed to create a fine air bubble with the least amount of pressure possible and it works best in deeper ponds (from 8 to 50 feet). It provides your pond with continuous (and quiet) work by requiring minimum maintenance from your part.

This aeration system will splendidly deal with algae growth, organic bottom muck, foul odors, excess nutrients, and fish kills. It will allow this little ecosystem of yours to thrive and you to enjoy it fully. 

If you happen to swim in your pond, then you will appreciate the fact that there’s no electricity in (or anywhere near) the water in the case of this highly requested system. Everything is submerged and hidden so nothing will bother you, no matter if you’re in the water or only looking at your landscape.

Robust-Aire pumps the water up directly from the bottom. It’s capable of injecting air 50 feet deep. It’s the best option for deeper reservoirs, as a floating fountain or surface aerator may not be enough in these cases. 

It’s not expensive both to buy and to keep. It’s energy-efficient and it requires low maintenance and almost no equipment to deal with.

Plus, you get a 3-year warranty on all elements. Let us know if you have any more questions.

Great System!!

The RA-2 is a well built system, works great and was easy to install. When I first called Living Water Aeration and left a message EJ called me back in a couple of minutes and helped me pick out the system best suited for my needs.

Kasco - RA2 System installation

Overall experience was great. Product was exactly as advertised. Required assembly was quick and easy. Needed 2nd set of hands to hold weighted hose on dock while I went out in boat and placed but that was expected.
