4+ Acre Pond Fountains

Pond Fountains for 4+ Acre Ponds and Small Lakes

Once a pond passes four acres, a single fountain stops being decoration and starts being water management. At this size we recommend 5 HP to 7.5 HP units such as the Kasco 5.1JF, 5.1VFX and 7.3JF, the larger Otterbine Concept 3 fountains, or the Scott Aerator 5 HP Gusher and Great Lakes. Large or irregular lakes are usually better served by two smaller fountains placed apart than by one giant unit, and most 5 HP and larger motors run on 230V single-phase or three-phase power.

Quick sizing guide: plan on roughly 1.5 HP per surface acre if the fountain is also your main aeration, or about 1 HP per acre for display only. Keep at least 3 feet of water under the float, and check cord length against the distance to your power source.
