Hydor Koralia Nano Aquarium Circulation Pump

Hydor Koralia has gained a cult status among fishkeepers for being the ultimate aquarium powerhead. Its popularity is mostly due to its unmatchable quality.

You will understand the difference between a cheap product and a Hydor powerhead simply by looking at the build quality.

The flow rate is fairly high and controllable – adjustable flow rate is rare in powerheads.

Also, aquarists heavily praise its magnet-suction cups.

Overall, this is the best aquarium powerhead you can find in this price range and it serves both freshwater and saltwater tanks.

There are two features which make the Cobalt Aquatics MJ Water Pump (MJ400) my favorite option:

  • Ultra-strong impeller
  • Installation mechanism

The strong impeller makes it one of most durable powerheads on the market. In addition, this powerhead comes with one of the best installation mechanisms.

Also, you will experience almost silent operation with this powerhead.

However, the low flow rate can be a problem. Luckily, there are four different models if you have a large tank.

Buying Guide: How to Choose an Aquarium Powerhead

An aquarium powerhead is an incredibly useful device as it creates water and air circulation. As a result, fish and plants can experience an almost natural environment.

However, you can’t just choose any powerhead from the shop and use it in your aquarium because this could cause several serious accidents in your tank.

For example, a poorly-made powerhead can create currents which are too high or too low. Such conditions will make your fish agitated. Also, you could experience voltage leakage which could even kill your precious fish.

Therefore, it’s important to choose wisely.

When buying, you should consider the following factors:

Aquarium Tank Size

Tank size is the first and most important factor to consider. A mismatch between tank size and the capability of the powerhead can easily lead to an issue of overpowering or underpowering currents.

There is another issue which is connected to aquarium size – the number of fish you have. Naturally, a large tank will house more fish. The more fish you have, the more waste will be created in the tank.

In such cases, a stronger powerhead is necessary to drive waste to towards aquarium filter intakes.

Generally, it’s hard to find powerheads which can sustain tanks larger than 100 gallons. In this case, you should purchase multiple powerheads in order to balance the load.

Water Flow Rate

Typically, we determine the power of a powerhead by flow rate. This means that the more water a powerhead can circulate per hour, the stronger it is.

So, you MUST check the flow rate of the powerhead.

Generally, this is measured in gallons per hour (GPH) or liters per hour (LPH). The GPH rating should be 5x the total water volume of the tank.

For example, if you have a 30-gallon tank, the ideal powerhead should have a flow rate of around 150 GPH (567LPH).

However, the 5x rule only applies for freshwater tanks. For saltwater tanks or reef tanks, you will require even more powerful powerheads.

For example, the Hydor Koralia Nano Aquarium Circulation Pump (Koralia 565), which takes the number one spot today, can satisfy the needs of a 65-gallon freshwater tank. But when it comes to saltwater tanks, it can only satisfy the needs of a 40-gallon tank at best.

Aquarium Types

I have already mentioned this factor in the last section. You must choose a powerhead based on the type of aquarium and its number of inhabitants.

You might think that there are only two type of aquarium, but you’d be wrong.

These are the common classifications of aquarium:

  • Freshwater tanks
  • Saltwater tanks
  • Reef tanks  
  • Axolotl tanks
  • Planted tanks
  • Turtle tanks

Obviously, the list doesn’t end here, but these are the most common ones.

Each of these aquariums has different characteristics, and therefore each of them have different needs from their powerheads.

For example, a turtle tank doesn’t require a powerhead, an axolotl tank might need only low-powered powerhead, but a powerhead is a must for a deep freshwater or saltwater tank.

The most important thing is that you need a powerhead for a deep tank.  

Why is that?

Because it offers better oxygenation and water circulation.

Sound Levels

A good powerhead is always silent. I would call this trait the identifier.

Not every brand specifies the noise level (dB rating) on the packaging, but if you see a brand which tells you the noise level, you should understand that that brand cares for you.

Sadly, there is NO powerhead on the market which is TRULY SILENT. There will always be a humming or buzzing sound.

But there is a way out!

Choose a powerhead which remains submerged while it works. This way, the sound will be muffled.

Also, you can follow my method – always read reviews from buyers. These can give you a proper idea of the noise level of a particular powerhead brand.

Aquarium Powerhead Brands

A BIG warning – don’t buy a powerhead from any unknown brand.

This is a common mistake which is made by new aquarists or fishkeepers. They are not to blame – there are a lot of cheap brands which offer tons of features and sometimes look flashy!

But they won’t last long. Actually, they might even break down after only a few days or weeks.

The noteworthy brands do their homework and produce excellent products. So, almost all of their devices are “battletested.”

This is the biggest reason to choose a product from a well-known brand.

Here’s a list of some of the most trusted brands:

  • AquaClear
  • Aqueon
  • Hydor
  • Marineland
  • KEDSUM
  • Cobalt Aquatics
  • SUNSUN
  • Fluval powerhead
  • Jebao
  • Current USA
  • Hygger

These are the top brands in the aquascaping industry and have years of collective experience creating top-notch products.

What is an Aquarium Powerhead Used for?

In a word, the main purpose of a powerhead is circulation. It circulates air and water.

Why is circulation so important?

Well, if aquarium water remains stagnant for a long time, high levels of toxins and CO2 can accumulate. This issue is more prominent in the bottom corners and around rocks and corals. Even filters don’t help much in some cases.

Over time, such water conditions can cause different diseases.

You can expect the following when you install an aquarium powerhead:

  • Cleaner and healthier water
  • Less debris and physical waste
  • Almost natural water flow in the aquarium
  • Healthier plants and fish  
  • Less algae growth
  • Proper distribution of nutrients

What is the Best Powerhead for a Reef Tank?

A reef tank requires a powerhead more than any other type of tank. The presence of corals and rocks creates several blind spots where water flow is almost non-existent.

But the question is what is the best aquarium powerhead for reef tanks?

In my opinion, the Hydor powerhead is best option for a reef tank. The development team at Hydor recommend using different settings to meet the requirements of a reef tank. This shows their expertise and commitment. Also, the specs list is praiseworthy.

If you are on a tight budget and intend to buy something cheaper, you should go for the SUNSUN JVP Series. This powerhead is specially designed for saltwater and reef tanks.

I should clarify that both of these products are somewhat entry-level powerheads. There are a lot of more powerful and expensive professional-grade powerheads available on the market, such as the Tunze 6055.000 Nano Stream with 7090.500 controller.

Best Powerhead Placement for Saltwater Reef Tanks

Typically, you should place the powerhead on the side wall of your aquarium. This way, you can create uniform water flow all over the aquarium.

For a small aquarium (20 to 40 gallons), one single powerhead is enough, but for a larger tank (60 gallons plus) or a deep tank, you should use two instead of one.

If the tank is too deep, you install a powerhead in the bottom corner to create agitation in the water in lower areas.  

However, powerhead placement is very much dependent on the type of coral you keep in your tank. Some corals enjoy a stronger current while others cannot stand it.

So, you should act accordingly.

Where Should You Put a Powerhead in a Planted Aquarium?

As with a reef tank, the placement of a powerhead in a planted tank is quite tricky and depends on the species of plants.

Some plants thrive well in strong currents and some don’t.

However, you shouldn’t place the powerhead towards the bottom as the strong current can damage or weaken the roots. It’s better to place it on the back or side walls so that plants can obtain enough nutrients without any damage being caused to the roots.

How Does an Aquarium Powerhead Work?

An aquarium powerhead is a simple device. Its main mechanism is to suck in water at one end and push it out the other end.

The basic construction consists of a propeller chamber, a propeller, a motor, and an installation mechanism.

When you turn on a powerhead, the motor starts and moves the propeller. Due to centrifugal force, the water enters the propeller chamber and exits the chamber. Centrifugal force also creates a vortex. And finally, this force creates a wave which stirs the whole aquarium.

A suction cup or a magnet will hold the device in one place.

How Do You Install an Aquarium Powerhead?

The installation process is entirely dependent upon the installation mechanism. Some devices use suction cups (most common), some use magnets, and some use clamps.

Firstly, you should read the user manual and check the installation mechanism. Then, you should either attach the cups or use the magnets on the side of the wall.

When doing so, make sure that any wires are not in the way. Also, you must keep the device underwater or it won’t work.

Finally, plug it in to the power outlet. It’s always wise to plug it directly into the wall to avoid nasty accidents.

So, there are only really two steps for installation:

  • Attach the suction cups or magnets while keeping the device underwater
  • Plug the powerhead into the power outlet on the wall

Conclusion

Who is the winner today? Who claims the title of best aquarium powerhead?

Well, I think you already know the result! The winner is the Hydor Koralia Nano Aquarium Circulation Pump.

Cobalt Aquatics MJ Water Pump Multi-Purpose Powerhead follows Hydor, but misses out on first place by the tiniest margin.

SUNSUN JVP Series Submersible Circulation Powerhead Pump steals third place for being the budget champ.
