Garden ponds are a popular feature and can be found in many homes across the UK. In most instances, homeowners choose to install either a waterfall or fountain, or sometimes both. This of course means that a pump is required to circulate the water round the pond or to the fountain. If you are looking to create a garden pond that will require a pump, there are a few things that you should know first to ensure that you get a suitable solution and to keep the pump working properly.
There are a variety of water pumps that could be used in your garden pond, but which won’t deliver the best results. One type of water pump that isn’t really suitable is sump pumps, which tend to be too big and powerful to be utilised in a pond setting. These types of pump are not designed to be constantly running and doing so can reduce their lifespan. Pool pumps can also be used, but as they are external solutions, they aren’t ideal either. What you really need is a submersible pump that is designed for use in a garden pond.
In terms of size, you need a pump that is able to circulate the entire volume of the pond every 2 hours – or 12 times per day. This will create the most suitable environment for your fish and plant life. So, before you buy a pump, you need to have a rough idea of the size of your pond. Once you have this information you can then divide it by 2, to give you an idea of the number of litres per hour the pump must be able to circulate. If for example your pond holds 6,000 litres of water, you will require a pump with a flow of between 3,000 and 4,000 litres per hour. It is also advisable to go for a reputable pump manufacturer rather than trying to save a bit of money by going for a cheaper option. These pumps need to be able to operate in harsh environments day after day, and budget models are likely to fail, which can cost you more in the long run.
One of the key considerations when installing a pump is to select the right hose. Be sure to get some that is wide enough to deal with the water flow. Also, choose hose that is ribbed and which can be easily manipulated, without the hose being closed, which can impact on water flow. When you install the hose, make sure that you do not leave it excessively long, which may put unnecessary strain on the pump.
If you are planning a water fountain then don’t forget to place a bio filter sponge in the suction inlet pipe. This serves to filter out the larger particles that can be present in pond water and is especially important in the summer months when there are high levels of algae.
In order to keep your pumps running at their maximum potential there are a few tasks that you must undertake throughout the year. First of all, you need to clean out the pump filter every now and then. Usually 4 times a year will suffice, but if your pond is getting especially murky it could be time to give the filter a clean. If you keep koi carp in the pond then you should try and clean it more often, as the fish prefer cleaner water - plus you can see them easier! Most keepers of koi carp will try to clean the filter once a month. Whilst you are cleaning the filters it is a good idea to give the hoses a quick once over to make sure that there aren’t any splits or loose connections anywhere.
