Couldn't load pickup availability
Kasco Home Series is a compact bottom-diffused aeration package for small residential ponds. A shore-mounted 1/4 HP compressor sends air through weighted tubing to one or two single-loop diffusers on the pond bottom, creating continuous bottom-to-top water movement without placing electricity in the water.
DA1 or DA2?
| Pond size | DA1, 1 diffuser | DA2, 2 diffusers |
|---|---|---|
| 1/4 acre | 6 to 8 ft deep | 3 to 6 ft deep |
| 1/2 acre | 9 to 12 ft deep | 6 to 8 ft deep |
| 1 acre | 13 to 20 ft deep | 9 to 12 ft deep |
| 2 acres | Not recommended | 13 to 20 ft deep |
This is Kasco's starting chart for simple pond shapes. Irregular shorelines, coves, islands, shallow shelves, heavy organic demand, and long tubing routes can require a different layout. Send LakeTech a depth map or pond dimensions when the site is not a simple basin.
Compare the four packages
| System | Voltage | Diffusers | Weighted tubing |
|---|---|---|---|
| DA1 | 120V | 1 single-loop diffuser | 1 x 100 ft roll, 3/8 in |
| DAH1 | 208-240V | 1 single-loop diffuser | 1 x 100 ft roll, 3/8 in |
| DA2 | 120V | 2 single-loop diffusers | 2 x 100 ft rolls, 3/8 in |
| DAH2 | 208-240V | 2 single-loop diffusers | 2 x 100 ft rolls, 3/8 in |
What each package includes
- One 1/4 HP compressor in a stainless steel outdoor cabinet
- One or two single-loop diffuser assemblies
- One 100 ft roll of SureSink 3/8 in weighted tubing for each diffuser
- Ground-mount cabinet configuration
The optional vertical-structure mounting bracket, Kasco part 774440, is sold separately.
Home Series or RobustAire?
- Choose Home Series for a relatively simple backyard pond under 2 acres when one or two diffuser stations and the included 3/8 in tubing fit the layout.
- Compare RobustAire for larger or more complex waterbodies, three or more diffuser stations, longer or higher-flow tubing layouts, or an AireGuard cabinet.
- Aeration supports circulation and oxygen distribution. It does not directly kill weeds or algae, and severely stratified ponds may require a gradual startup schedule.
Warranty and planning
- Lifetime manufacturer warranty on the diffuser
- 15-year manufacturer warranty on weighted tubing
- Two-year manufacturer warranty on the cabinet, compressor, and external parts
- Confirm voltage, cabinet location, ventilation, tubing routes, diffuser placement, and qualified electrical installation before ordering.
