 How to Choose the Right Pond Pump

Choosing the wrong pump is the most common mistake pond owners make. Here's what to consider:

Flow Rate (LPH)

Your pump should turn over the full volume of your pond at least once per hour. For a koi pond, aim for 1.5–2× turnover per hour. Use our free Pond Volume Calculator to work out your pond's capacity before choosing a pump.

Head Height

If your pump needs to push water uphill to a filter or waterfall, account for head pressure. Every metre of vertical rise reduces a pump's effective flow rate — check the head pressure curve in the product specs.

Running Costs

An energy-efficient pump running 24/7 can save hundreds of dollars a year compared to a cheap, power-hungry model. OASE and PondMax pumps are engineered for low energy consumption without sacrificing flow — worth the investment for long-term savings.

Submersible vs. In-Line

Most pond pumps sold in Australia are submersible — they sit in the water and are simple to install. In-line(dry-installed) pumps are mounted outside the pond and suit larger setups where access for maintenance matters. Not sure which suits your build? Call us on 1300 238 288.

Frequently Asked Questions — Pond Pumps

What size pond pump do I need?

Match your pump's flow rate (in litres per hour) to at least 1× your pond's total volume per hour. For koi ponds, use 1.5–2× turnover. For example, a 5,000L koi pond needs a pump rated at minimum 7,500–10,000LPH. Use our Pond Volume Calculator to get your pond's volume first.

Should a pond pump run 24 hours a day?

Yes — for ponds with fish, the pump should run continuously to maintain water oxygenation and keep the biological filter active. Turning it off overnight can cause ammonia and toxin levels to spike, stressing or killing fish.

How long do pond pumps last?

A quality pond pump from OASE or PondMax typically lasts 3–7 years with proper maintenance. Regular cleaning of the impeller and pre-filter sponge extends pump life significantly.

What's the difference between a pond pump and a water feature pump?

Pond pumps are built for continuous heavy-duty use, handling debris-laden water and driving filtration systems. Water feature pumps are designed for cleaner water in decorative features like fountains and statues. Using a water feature pump in a fish pond risks premature failure.

Do you ship pond pumps Australia-wide?

Yes — we ship all pond pumps nationally from our Melbourne warehouse. Most metro orders arrive within 3–5 business days. Free or flat-rate shipping available on qualifying orders.
