Pond-One

Why Pond-One

Two clean ladders of flow rate and nothing else to think about. That is genuinely useful when the only real question is how much water or air you need to move.

Fountain pumps for circulation and features

The Pondmaster range runs 2800L/h, 3500L/h and 5000L/h. Those are the sizes that suit a feature, a small waterfall or general circulation on a domestic pond.

Air pumps for oxygen

The O2 Plus range covers 2100L/h, 4200L/h and 6600L/h of air. Aeration matters most in warm weather, when water holds less dissolved oxygen exactly as fish and bacteria demand more of it.

Aeration is not the same as circulation

A water pump moves water and adds some oxygen at the surface. An air pump puts air directly into the water column through a diffuser. A pond with fish through an Australian summer generally wants both.

Our Pond-One range

Pondmaster fountain pumps: the 3300 at 2800L/h, the 3600 at 3500L/h and the 4900 at 5000L/h.

O2 Plus air pumps: the 4000 at 2100L/h, the 8000 at 4200L/h and the 12000 at 6600L/h.

Sizing pond equipment

1. Aim to turn the pond over about once an hour. A 3000L pond wants roughly 3000L/h at the height you are actually pumping to, not at zero head.
2. Account for head height. Every pump loses flow as it lifts. Read the curve at your real lift, not the headline number.
3. Aerate more in summer. Warm water holds less dissolved oxygen. That is when fish are most active and bacteria are working hardest — the worst possible combination.
4. Keep the pump submerged. Submersible pumps use the surrounding water for cooling. Running one dry kills it quickly.
5. Clean the intake regularly. Leaf litter and string algae blocking an intake is the most common cause of a pump that has "stopped working".
