Best Aquarium Powerheads Of 2019

All aquariums require the right filtration system to maintain the quality of water. Whether you have a saltwater, freshwater or a reef tank, a filtration system is a must.

But even after installing one, your tank is not thriving, it might be because your tank is missing something.

For this purpose, you may install a powerhead in your aquarium to make sure that it has the perfect environment for the marine life.

What is the use of an Aquarium Powerhead?

It is important in an aquarium that the water keeps moving. Continuously moving water helps the corals, plants, beneficial bacteria, and all the marine animals to thrive well.

For this purpose, a powerhead comes to the rescue. It is a type of pump that is placed underwater in your aquarium to create a nice current, by keeping the water moving around the tank and causing the heater to heat the water.

There are some dead spots in an aquarium, where the water does not move. The spots directly in front of the filter circulates multiple times while the water in the corners does not get any treatment.

The best way to make sure that the water circulates through the entire tank, is to use an aquarium powerhead.

Points to consider before choosing an Aquarium Powerhead

Before picking the right powerhead for your aquarium, here are some points that should be considered:

AQUARIUM TANK SIZE

For large-sized aquariums, a powerhead is a must. It keeps the fish waste away from collecting in the corners and into the filter.

If you have an aquarium more than 100 gallons, you must consider getting more than one powerhead so as to make sure that the current reaches all the four corners.

WATER FLOW RATE

Powerheads are rated by how many times the tank water is circulated every hour.

Flow rate is measured in gallons per hour or GPH. Remember that you will need to re-evaluate the tank flow rate as it will grow and expand.

SOUND LEVELS

If your tank has a heater and a filter, you might not want to add a powerhead to it. But keep in mind that since powerheads are designed to be installed underwater, the noise is usually muffled. So you need not worry!

Just read the reviews of the model online before purchasing.

AQUARIUM POWERHEAD BRAND

Brand reputation matters when it comes to powerheads. Some of the best brands are: Hydor, SUNSUN, Cobalt, Penguin, and AquaClear.


TYPES OF AQUARIUM

If you have a freshwater or saltwater tank, the kind of powerhead you need will depend on it. They won’t use the same powerhead which will fit a reef tank. So the type of setup your aquarium has, will affect the choice.

What is the Best Powerhead for a Reef tank?

For small reef tanks, Hydor Koralia Nano Aquarium Circulation Pump is the best pick. It is very easy to install because of the suction cups. Plus, you can place it anywhere inside the tank due to its compact size.

The best thing is that it runs very quietly, so that the marine life is not disturbed.

You may also adjust its flow rate with a simple ball joint, which rotates a full 360 degrees. It means that the water flows in all directions, to give your tank a natural, ocean-like current.

This powerhead comes really handy as your reef tank continues to grow overtime, as it is very easy to make adjustments.

How does an Aquarium Powerhead works?

Powerheads can be used for different purposes apart from the basic one which is to circulate water inside the aquarium. They have sealed motors which keeps them safe when submerged underwater.

How a particular powerheads works, is very simple yet interesting. It pulls the water on one side and force it to the other side through an outflow spout. To get control over the movement of current inside your tank, you need to notice the position where you place it.

The current created by a powerhead moves the water in all directions, which are out of reach of the filter. It thus helps in losing the debris that is settled at the corners and makes its way towards the filter for removal.

The more the water circulates, the cleaner it will be and there will be less chance of algae growth. It will also help the fish, coral, and plants to stay healthy, as moving water will bring them oxygen and food.

A powerhead is an effective and economical way to make all of the above happen.

How to Install an Aquarium Powerhead?

The basic installation process of an Aquarium Powerhead goes like this:

  1. Place the powerhead inside the tank.
  2. Now plug it into the outlet.
  3. Keep the plug dry and plug it directly into the wall.
  4. Make sure the power cord is out of the way, so that no one can trip over it.

SAFETY CHECKS:


  • Examine the powerhead to make sure there is no crack or damage.
  • Make sure to keep the power cord away from the water.
  • Make sure that the water does not splash the plug.
  • Never use a powerhead with an extension cord.

Where to Place the Powerhead inside an Aquarium?

There are a few factors to be considered before placing the powerhead inside the aquarium:

  1. Consider the kind of organisms you are keeping in your tank, as some will thrive well with strong current while some won’t.
  2. For tanks with live, growing water plants, try mimicking the natural environment of the bottom of a lake or ocean.
  3. For saltwater reef tanks, it is important to mimic the natural environment using powerheads. Since corals are far less forgiving than planted tanks, it is important to get it right.
  4. Consider the tank size before buying a powerhead: For tanks less than 20 gallons, one powerhead will do, while those more than 20 gallons, will require multiple pumps because the force from one powerhead will be able to more the water in only a small section of the tank.
  5. If you want to oxygenate the tank and create some surface movement, place the pump closer to the surface, not underwater.
  6. If you want to create a deeper current, place the powerhead at the bottom.

Conclusion

Even the right filter media is not enough to keep the aquarium environment healthy. This is so because filters can only clean the water right in front of them, which encourages the same water cycling through the entire tank, while stagnant water sitting at the bottom or in the corners.

An easy and affordable way to tackle this is using an aquarium powerhead. While powerheads are usually misguided as a second filter, their main purpose is to create current inside the aquarium, to let the water cycle more efficiently.

Getting the flow rate inside an aquarium right, has a lot of benefits like, delivering food, vitamins and minerals effectively and encouraging the fish to stay active.

It is also important to research the living organisms inside your tank, as some plants do not like strong current while some thrive well in it. This is particularly important for corals as they are really sensitive.
