It’s great having a pond at home, but to keep it looking its best and support the fish and plant life of your choosing, you need to invest in a good pond pump. To choose the right pump for your pond, there are many factors that you will need to consider. These factors include:
- The size of your pond (how many litres it contains, i.e. the total volume)
- The water features in the pond and their individual requirements
- The plant and fish life that your pond will support
- The water filtration system that you’re going to use in the pond
- The distance of the water filtration system from the pond
Each of these factors is very important and you need to spend a good amount of time planning your pond and working out which pond pumps are the most suitable. It’s always a good idea to consult an expert as well, so ask for advice at the store or online retailer where you’ll buy your pump.
Work Out the Volume of the Pond
The first step that you take should is to calculate the volume of water in your pond. To do this, follow the following formula for rectangular ponds:
- Multiply pond length x pond width x pond depth x 1000
This will give you the volume of your residential pond in litres, which is the measurement that most retailers work with. For ponds with an uneven shape, calculating the exact volume of water can be difficult. One of the best ways to get a reasonable estimate is to take the measurements of the pond from the deepest and widest points in the pond.
Determine the Flow Rate
As a rule of thumb, the required flow rate of your pond should be at least half of the total volume of the pond, so once you’ve worked out the pond volume, you can then easily calculate the required flow rate. For example, if your pond was 500 litres, you need a flow rate of at least 250 litres per hour, which really isn’t very much when you look at the flow rate of some of the top pond pumps on the market these days. However, if you’re planning to have water features in your pond, which is great, like a fountain, waterfall or something similar, then you’ll need a greater flow rate.
As mentioned earlier, it’s always a good idea to consult a pond professional, someone with a good deal of experience in ponds, pumps and water filtration devices. That means you need to source a good online store, one that’s happy to advise you on your requirements so that you can rest assured that the pond pump you purchase is the right one for your pond and the aquatic and plant life that it supports.
It’s hoped that this short article has proven interesting and that it helps you to make the right decisions about the pumps and water filtration devices that you purchase for your pond at home.
