Whether you are new to aquarium activities or an experienced
one, your main objective is to have a healthy and thriving aquatic environment
for your water plants and animals. To achieve that, one of the most important
things that you need to do is to make the right decision when choosing the
right aquarium water pumps.
When you want to buy a water pump, there are several things
that you need to consider. Apart from the type of water pump and the size,
there are also some other important things that you need to look at. Here are
things that you need to look at when choosing an aquarium air pump.
It is crucial for you to know the type of filter system that
is best for the type of aquarium that you are planning for. Actually, the type
of filter paper that you choose will determine the type of water pump that you
Desired flow rate
You need to know if the inhabitants of your aquarium, either
fish or aquarium plants require a greater flow rate of the water like the
saltwater fish or just a little flow rate like the planted aquarium. You,
therefore, need to research on the flow rate that is fit for the type of
aquarium that you are planning for.
Plumbing and head point
You need to know the type of plumbing that will be installed
in your aquarium. Are you going to use a lot of elbows or sharp turns in your
aquarium? You also need to know where your filtration system will be located.
Will it be directly under the aquarium? Will it be in the basement or in
another room? It is also important to consider the total distance the pump will
be required to pump the water.
Height is also an important thing that you need to consider when choosing a water pump. This is because very high heights which are more than 6 feet create high levels of back pressure.
You also need to know if your aquarium will need additional
filtration services or not. Will it require temperature control devices like
the UV sterilizers or not? Protein skimmers or chillers?
You need to know that apart from the water pump powering
your filtration system and enabling water movement in your aquarium, water
pumps also help to power other devices that are important in the aquarium like
the protein skimmers. They also help to drain or fill the tank. Apart from all
those, water pumps also help to mix up salty water in holding tanks for water
If you are looking for a water pump to power your filtration
system, there are two different types that you can consider to buy. You can buy
the submersible one or the he in-line one. You can also consider buying water
pumps like Mag Drive Pumps and the Eheim hobby pumps that can be used both for
submersible and in-line purposes.
Submersible water pumps
Submersible water pumps are operated underwater, in the sump
of a wet/dry filtration system. They get draw water from the filter and push it
back to the tank or through other systems such as sterilization units or
Advantages of submersible water pump
They are easy to install. They do not require
you to bore and install bulkhead in the filter system.
They are also quiet compared to others as they
operate under the water.
Disadvantages of the submersible water pump
There is a big problem with big pumps. This is
because this type of pump is water cooled. This means that water around the
system will be subjected to heat which cannot be suitable for the fish in your
For the big pumps also, there will be a little
space for the pump in the filter’s sump. So, you need to consider the dimension
of the submerged pump before buying it.
In the case of the pump getting damaged it will
be difficult to note it faster as it is inside the water. It, therefore, should
be checked from time to time.
In-line water pumps
These types of pumps are used outside the water. They are
connected to an inlet hose and outlet hose used to filter the water in the
Advantages of an in-line water pump
This type of water pump is air cooled. This
means that it does not result in the heating of the water.
They are more powerful. They are able to pump
more gallons of water per hour.
In-line pumps can be installed in one or two configurations.
There is the pressure set up and the free-flow configurations. One example of such pumps that can be
installed in two configurations is the Lifegard Quiet One. Other types of
in-line pumps can only be used in one configuration.
In-line pressure setups
Here, the filter is placed before the canister filtration
system. The pump pushes water under the pressure into the canister system.
Pumps in this set up receive a considerable amount of back pressure from the
filtration device. There are some like Little Giant MDQ series that are
specifically designed to handle back pressure with much ease.
In-line free-flow setups
In this set up the pump is placed after the filtration has already taken place. The pump moves the filtered water from the sump back into the aquarium or through UV sterilizers or protein skimmers. They are, therefore, able to pump more water with less effort. Some like Little Giant MDQX series are built for maximum efficiency in low-pressure situations.
