  • Many sellers of pond keeping equipment including pumps will have a limited knowledge of what is important and what isn’t. They may provide you with inadequate information or be biased in favor of a particular range of pumps (monthly sales targets etc.
  • Beware of a garden pond pump that appears to be very cheap or one that you haven’t heard of before … read articles and forums on-line. The internet is an excellent source of advice and recommendations. The major consideration for any pond pump is the running costs, bearing in mind that a pond pump needs to run continuously.
  • Look at the manufacturers warranty and the length of power cord supplied … 2 years is the minimum that you should consider. 10 meters of cable is also the minimum I would consider. Of course you can always buy an extension … but why would you want to do that?
  • Are you after a pond pump simply to supply water to your pond biofilter or are you trying to create a waterfall or fountain effect. Choosing a submergible fountain pump (submersible fountain pump) will save you the added expense of adding a fountain nozzle attachment later. A good fountain pump will incorporate a strainer device, to prevent pond solids and debris from blocking the nozzles.

A Biological Pond Filter Is Critical

A biological pond filter is an absolute must for any garden pond environment, as it is responsible for purifying pond water and helping to keep your garden pond clean.

Surely the idea of a pond is to have crystal clear pond water which allows you to see your ornamental Koi, gold fish etc.

Buying the best pond pump in 2018

Deciding on a pond pump can be a confusing process, yet is important for the sake of your pond’s fish, beauty, and electric usage. Pumps that are not self-priming can burn out a motor if the power shuts off momentarily and then returns, so protect against this by installing a check valve. These pumps are designed to be used in multiple applications, from spillways to fountains,but ultimately their major purpose is providing flow for water features. You may find that 1,000 gph is not enough if you plan to have a waterfall that is more than 10 inches wide. Pond pumps have the ability to power both waterfalls and fountains as well as create circulation.

  • Do not generate high head heights, meaning it is unable to lift pond water vertically, which you might need to supply water to a fountain.
  • And although these pumps would in many case provide adequate flow for a Pond Filter, the major characteristic of these pumps is that they are designed to pump water vertically.
  • Generally for a waterfall you will want 100 – 150 gph per inch of width of the weir (the portion that the water spills over). This amount will vary depending on how smooth or rough the weir is.
  • To maximize the performance, it is important to choose the correct mixture of pump and fountain head, otherwise your pond may end up with insufficient circulation and lead to an unhealthy pond that is low in oxygen.
  • Since they have no seals to wear out, they require little maintenance.

This is specified on each pump model as the Head Height. If you want less than a full flow then less flow is acceptable. This pump is for larger ponds with 1000 to 1500 gallons. Any pond worth its name must have a filtration system. If you have two ponds interconnected with a stream or waterfall you should measure them both and add the totals together.

You will also need to consider your filter and ultraviolet sterilizer (UV) to make sure that you are moving the right amount of water for these devices. They can also power waterfalls up to a maximum height of 13 feet. Without this device, your pond will quickly turn into a nauseating swamp. Doing this will avoid long terms problems associated with inadequate filter size or insufficient water turnover for the volume of the pond. It is important to know the approximate number of gallons in your water feature to be sure that insufficient circulation does not occur.

This item features a ceramic shaft that is both water resistant and anti-corrosive to extend the life of the pump. The primary purpose of the filter pump is to recycle the water in a closed circuit through a filter. Insufficient circulation can cause areas of stagnant water, unacceptably low oxygen levels, lack of proper filtration, and many other things, which will eventually lead to an unhealthy pond. This filtering removes any suspended particles and/or waste from the pond (dead leaves etc.). In general, a filter pump is instantly recognizable due to it’s large filter – normally at least 10 mm. Unhealthy ponds are not good habitats for fish and plants, and will become an unpleasant addition to the backyard.

The secret to maintaining a beautiful, crystal clear pool, whether it be to keep goldfish, ornamental Koi or other fish species is to ensure that the water is kept free from ammonia, nitrites, suspended algae, parasites and harmful bacteria.

Do not make the mistake many new pond keepers make! Follow the advice and recommendations on this site and you will not only save $$$ but provide a healthier, safer place for your fish and aquatic life to live in …

Choosing the right product the first time around will save time, effort and money! There are 3 essential pieces of equipment needed to ensure that you achieve your goal of a crystal clear, clean and healthy environment for all your fish to live in:

Total pond gallons can be determined by connecting a water meter to a garden hose while initially filling the pond. A small pump designed to operate features such as pebble pool fountains, ornaments or small self contained features. To determine the correct submersible pond pump for your water garden, you should determine your pond’s volume. There are many things to consider when purchasing your pond pump. To calculate the approximate volume, multiply the pond’s length in feet x width in feet x depth in feet x 7.5.

They really aren’t suitable for use in a garden pond due to the size of prefilter. It is recommended that you circulate your pond’s water once at least every 2 hours. If you have a basic pond with very few fish, or simply keep your pond as purely ornamental, the calculations are very straight forward. In addition to circulating water, pond pumps are often required to lift water. Most models come with selected fountain attachments as standard.

Hence, your pump should have a GPH (gallons per hour) rating of at least half of your pond size. However, once you start adding various types of equipment, such as a pond filter, or, more fish, or require a waterfall, your pond requirements will differ dramatically from the basic calculations. Head height is the vertical distance the pump must raise water above the surface of the pond. More importantly, a pump will assist in maintaining the health of your pond by circulating and aerating the water. Calculating the proper pump for waterfalls is a bit trickier, because waterfall pumps are rated by both GPH and maximum waterfall height.

The greater the head height, the harder your pump will have to work. Good aeration will mean that oxygen levels in the water will be kept high even during the warmest weather, when fish could otherwise be at risk. To estimate your waterfall’s height, you must measure the vertical height from the top of your pump to the top of your waterfall or stream.

If you have fish in your pond, you want more filtration. For most ponds with Koi we recommend that you pass the water in your pond through your filter every hour, therefore at a minimum your pump should be big enough to do this. Waterfalls add beauty and serenity to a pond while keeping the water moving to avoid stagnation. These models are placed outside of the pond, usually hidden in a bush. For most pond setups, the main pump drives water through the filtration system; so more flow equals more filtration.

So a 5000 litre pond would need a minimum of a 5000lph pump. To keep water flowing over your waterfall, a pump continuously moves water from the pond below to the top of the waterfall. They are more powerful and more cost-effective. A safe bet is to double the flow if you have fish – so for a 1,500 gallon pond, you will want 1,500 GPH of water flowing. Your filtration system’s capacity also needs to meet your desired flow rate.

The taller or wider a waterfall is, the more powerful your pump will need to be to circulate the water. On the other hand, these devices will be more expensive are more audible than their submerged siblings. Having extra flow will help your pond support more fish, but you want to be careful not to exceed what your pond can handle. If you have 5000 litres of water your filter needs to be able to handle a flow of more than 5000 litres per hour for your water to turn over hourly. If you have a waterfall installed, it’s important to choose the right pump for your pond to move enough water to keep the waterfall going. Additional pipes will have to be installed to bring the water to and from the pump. The flow returning from your filter will be less than the flow entering the filter.
