How to choose a pump for a pond?
General rule of thumb is to get a pump that can turn over your entire water feature 1. If you have a 1,000-litre pond, you should aim for a pond pump that has a flow rate of 500–1,000 litres per hour for perfect pond maintenance. This could be something like our Fish Mate Pond Pump 344, which can handle around 700 litres per hour.Ideally the correct pond pump to use would be a pond filter pump, as they produce the highest flow rates and require the least amount of cleaning. However in small pond situations, the side connection of a larger pond fountain pump could be used to feed a small stream or waterfall.Can a pond pump be too powerful? Yes, a pond pump with a large, un-adjustable flow rate can have disastrous effects on a small wildlife pond, creating whirlpool-like conditions that lots of fish and other aquatic life cannot handle.Turn on Your Fountain or Add One This is a very inexpensive method with the added bonus that your pond will benefit from an attractive water feature. Pond fountain pumps come in a wide variety of sizes so buy one that’s right for the size of your pond.
What size pump do I need for a 5000 litre pond?
What size pump do I need for my pond? As a rule of thumb and a minimum requirement, you want to turn over the volume of your pond water once every two hours, e. A 5,000 litre pond would have a minimum requirement of a 2,500LPH pond pump. Conventional advice is to select a filter pump that will turn over the pond volume once every two hours. That means that for a 10000-litre pond you will require a 5000lph pump.Pond stock The filtration and water treatment can also contribute to the number of fish you can have. We recommend 1-5 goldfish or 1-3 koi per 1000 litres, to ensure the fish can grow to its maximum potential.There is no hard and fast rule for stocking a pond with fish, but a good general rule of thumb is to allow 25cm (10) of fish per 455 litres (100 imperial gallons). This must take into account the eventual adult size of the fish.
