Kasco offers you an efficient and cost-effective way to keep your water oxidized. Why is oxygen so important? It reduces algae growth, the presence of excess nutrients and organic bottom muck. It helps to create the best possible environment for your fish and plants, plus, it makes it better for people who spend their time around - it reduces bad smells and makes the water cleaner. 

The Kasco Robust Aire Pond aeration system includes 2 single piston compressors, 2 dual-port aluminum manifolds with valves, four 100-foot rolls of 3/8 inch Sure Sink weighted tubing and 4 Robust-Aire diffuser assemblies. It is designed to keep the diffusers working at the right level above the bottom of the pond. There’s also a check valve with Viton seals to keep the water from entering the tubing.
