What size fountain does a golf course pond need?

Roughly 1 HP per acre is the standard starting point for water quality; a signature-hole display is often sized one step up for visual impact. Fountain Depot sizes units to your pond's exact dimensions at no charge.

Fountain or aerator for an irrigation pond?

Choose a surface aerator or diffused aeration when the goal is water quality and algae control; choose a decorative fountain when the pond is also a visual feature. Aerating fountains like the Kasco VFX split the difference.

Do we need three-phase power?

Not necessarily. Kasco's 3.1 and 5.1 models deliver 3–5 HP on standard single-phase 240V, which suits rural courses without three-phase service.

Who services the equipment after installation?

Fountain Depot is an authorized Kasco repair shop based in Markham, Ontario, serving the GTA in person and supporting courses across Canada with parts and replacement motors.

Frequently Asked Questions

Which RA model do I need for my pond?

Plan roughly one diffuser per acre in water 10+ feet deep. The RA1 covers a small pond, RA2-RA4 handle 1-4 acres, and the RA6 through RA12 serve multi-acre lakes. Shallow or irregular ponds often need more stations at lower depth rather than fewer big ones.

Where does the compressor go?

The compressor sits on shore in a weather-resistant cabinet - only the airline and diffuser go in the water. Electrical service only needs to reach the shoreline cabinet, which often makes diffused aeration cheaper to install than powered surface equipment on large ponds far from a panel.

Can I run RobustAire through winter?

Yes. Diffused aeration can run year-round. In winter, reposition the diffuser to shallower water to maintain a controlled opening in the ice for gas exchange and fish health. Keep replacement air filters and rebuild kits on hand for spring maintenance.

How long does shipping take?

Orders ship across Canada from stock. Delivery typically takes 3 to 5 business days depending on your province.
