Kasco RA3 Robust-Aire Diffused Aeration System Surface Aerators or in areasThe Kasco Marine RA3 Robust Aire aeration system is a great aerator for larger ponds up to about 4 acres in size (depending on the depth). Effective aeration can be achieved in 2 acre ponds 5 to 8 feet deep, 3 acre ponds 8 to 12 feet deep, and 4 acre ponds 12 to 16+ feet deep. Mark's Take: The Kasco RA3 has been a great performer for us over the years. Like all the Robust Aire systems, it's built like a tank solid throughout. I'd rate reliability near
