Submersible Water Pumps for Your Aquarium or Pond

Posted on Jul 14, 2020

Submersible Water Pumps

You need good submersible water pumps if you have a pond with a falling waterfall, a fountain decorated with elegant statues, or an aquarium with your favorite colorful fish. A pond pump will ensure a healthy and vibrant life in the water. But no pond pump is enough; it also has to provide reliable and energy-efficient performance so that you can save on water and electricity bills.

Why the water function requires a pump

There are three main reasons why your pond needs a pump:

1. Stops any pests from breeding in water

A water pump will prove to be an invaluable asset to any type of water function. The reason why the submersible water pump is such an indispensable tool is that without it there is no aeration because it pumps water into and out of the pond to maintain good water circulation. No water circulation means that the pond or fountain will run out of green stagnant water, which will become an ideal breeding ground for mosquitoes and other pests, which will change your once beautiful water paradise into a hell hole filled with dead fish and decaying plants.

2. Provides adequate water filtration

A pond pump in combination with a high-quality pond filter will improve water quality. These two cooperating elements will ensure that good bacteria remain in the water and eliminate the accumulation of bad bacteria, and also keep the water free from contaminants. The pump plus filter is clean water and a thriving aquatic environment that will attract all types of wildlife.

3. Maintains proper water flow

The water pump also maintains the correct water flow in the pond, which is especially important if you have an additional water function, such as a waterfall or fountain. If the pump has an incorrect water flow and produces too much water - gallons per hour (GPH) - your waterfall will be throwing out too much water, which will upset your fish and will look more like a whirling wave on the beach.


If the pump is not strong enough, your waterfall or fountain will be weak and inefficient and will look more like a dripping tap that has not been properly turned off. The right type of pump will ensure the correct water flow, thanks to which your waterfall or fountain will create the desired effect, either a delicate trickle or an impressive Niagara Falls water display that cascades beautifully into a rock formation or spray with an impressive arch into the catchment.


How to Choose the Right Pump?

A pond pump is a very versatile tool. It can be used for ponds, outdoor fountains, aquariums, desk fountains, and a hydroponic gardening system. Before you choose the right type of pump that will suit your water needs, here's a short lesson on how pumps work.


How Does a Pond Pump Work?

The pond pump uses a very simple style of operation. The electric motor is used to rotate the impeller, which draws water into one side of the pump, and then pushes water from the other end. The flow rate depends on the size and power of the rotor, which requires some output power (power) from the electric motor.


Money-Saving Considerations

Since most pumps are designed for 24/7 operation, they may have an overload switch that can stop them from overheating, but if you want to leave the pump in continuous operation, the cost-effectiveness of the pump is important.

To meet the growing demand for high-quality pumps that are inexpensive in the long run and will not overload the bank account, manufacturers are looking for ways to improve their machines to make their pumps profitable. Some manufacturers use magnetic motors in their pumps, which means that their pumps are energy efficient or can be designed to use lower power, while other pumps can only have one moving part, a ceramic shaft, and impeller, which means they require less maintenance.

All these innovative technological improvements will save you money on electricity and water bill


The Size of the Water Function

To be able to choose a pump suitable for the water function, the number of gallons per hour (GPH) that the pump can provide must match the size of the water function. Ponds, aquariums, and fountains come in all sizes: small, medium, and large, which depends on the amount of water they can hold. Small ponds have a capacity of 200 to 1000 gallons of water, medium ponds have up to 5000, and large ponds have 10,000 gallons of water and even more.

Some pond pumps, such as special submersible pumps, have a flow rate of 200 GPH and are recommended for small pools with a capacity of 200 to 400 gallons. The pond pump, which can generate 3100 GPH, fits well with a medium-sized pool. If you have a large pond with a capacity of 10,000 gallons, it is best to choose a pump that can generate 10,000 GPH so that it meets the water requirements and still works properly.


Submersible and External Pumps

Like pond filters, pond pumps can be designed to be submerged or placed anywhere around the edge of a water element.


Submersible Pumps for the Pond

Submersible pond pumps are a great choice for almost any type of pond or water function but work best in smaller ponds up to 1000 GPH. They are usually weaker so they may not be the best choice if you have a large fountain or want to have a large waterfall. They are very easy to set up, less noisy, and do their work out of sight under the water.

The disadvantage of using a submersible pump is that it clogs more easily and needs regular maintenance. If you have a pond with lots of fish and vegetation that can create a lot of trash, choose a submersible pump with a Pumpshield mesh bag that can prevent the pump from clogging by dirt.

If you have a medium-sized pond and want to choose a submersible pond pump, look for a model with a solid pre-filter that helps move hard dirt before it reaches the separate filter attachment. Submersible pumps are also very compact, which is an ideal choice for indoor aquariums.


External pond pumps

External pond pumps are placed outside the pond, so you don't have to worry about getting wet when you need maintenance, but this type of pump may require more complex installation and may be more expensive in advance.

External pond pumps can be used to pump and aerate water in small fish ponds, while other more powerful models work very efficiently in larger ponds, and some manufacturers design their pumps so that they can be used as an external and submersible pump.

Compared to submersible water pumps, external pumps can be bulky, and if you are worried about the overall aesthetic value of your water function, you can hide the pump by hiding it behind rocks or leaves, but it must be easily accessible for maintenance.
