Have you recently been to a public aquarium and now your children are requesting to keep fish as a pet? Have your children presented the argument that fish do not need much care or maintenance like canines or felines?
Well, they are wrong. Fish Aquariums have to mimic the natural habitat of fish like lakes, rivers, lagoons, and whatnot. And for that, we have to filter, remove salinity, and preserve nutrient cycles so that the fish have enough nutrients to sustain in this artificial water body.CHECK THE TOP AQUARIUM POWERHEADS NOW!
But if your children are adamant, you can do two things show them Finding Nemo or buy them an aquarium. In an aquarium, you will need equipments like the best aquarium powerhead that can circulate the water and create waves just like an ocean or laminar river current.
So after reading this article you will be able to decide which powerhead is best for your aquarium.
First, we will discuss the working and uses of an aquarium powerhead. Then we will move on to list the top ten aquarium powerheads of 2022. After that, you will learn how to place your powerhead inside the aquarium.
Let’s begin by the definition and uses of the aquarium powerhead.
What Is An Aquarium Powerhead, And Why Do You Need It?
Powerhead is a motor that is submerged in water to circulate water. Powerheads are rated based on GPH(Gallon per hour). If your powerhead is rated 100 GPH, it means it will move 100 gallons of water in an hour.
It is an integral part of an aquarium ecosystem; it circulates water that maintains the necessary oxygen level throughout the aquarium. Air stones are also used in an aquarium to maintain oxygen levels, but they are not as efficient as a powerhead.
Other than that they prevent waste generated from aquatic animals and other debris to settle at the bottom of the tank so that you can filter it easily. They also provide food to stationary animals in the aquarium. Water currents and waves also help fish to increase their physical activity.
We all know the disadvantages of stagnant water that it is a breeding ground for disease-carrying mosquitoes. Some algae also prefer stagnant water for flourishing, so your powerhead also prevents the growth of algae.
Some fish can’t survive in cold water, so you have to heat the water by using heaters. But if there is no powerhead, the heater will heat the water that is in front of it so that water will become warmer than required and the rest of the tank will be at a lower temperature. That is where your powerhead comes into play; it helps in maintaining homogeneous temperature throughout the tank.
Water circulation also prevents algae growth because certain algae prefer stagnant or less turbulent water. Algae growth is inversely proportional to aquatic plant growth as it deters the leaves to inhale carbon dioxide.
Some powerheads also come with directional flow diffuser that helps you to direct the flow of the water.
Factors To Consider While Buying the Best Aquarium Powerhead
Size Of Your Aquarium
If you get an aquarium powerhead that is too small and has weak power, it can’t circulate the water in your gigantic 50-gallon aquarium. It would be better to either get rid of it or buy two of them. While purchasing a powerhead, keep the size of your aquarium in your mind, and act accordingly.
Researchers have found that to keep a healthy aquatic environment, the water should be circulated 5 to 6 times in an hour. So if your aquarium’s capacity is 30 gallons, you should go for a 150(30×5) GPH powerhead. Having the rating of your powerhead ten times the capacity of your tank is enough, and you shouldn’t go higher than that because the delicate fish might die in a turbulent flow.
If your tank’s capacity is more than 100 gallons, you should think about investing in 2 powerheads or more as one wouldn’t be enough.
The Flow Rate Of Water And Types Of Fish
Different types of aquariums need different types of flow rates.
If you have a large fish as your pet, your aquarium will need higher flow rates and possibly additional powerheads to get as much fish detritus into the filter as possible, to remove it.
Reef tanks need higher flow so that water can move in all areas of the aquarium. It is essential for Filter Feeders (They are a subgroup of suspension-feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, baleen whales, and many fish.)
If you have live plants in your tank, then the best aquarium powerhead for you will be the one with a lower rating in GPH. Decreasing surface agitation helps hold in the CO2 much needed by plants for photosynthesis. Most plants cannot tolerate being in the middle of the flow stream, and that is the reason rivers have no aquatic plants thriving in them whereas in the deep ocean the flow is negligible and we can see ethereal plants.
Small fish, baby fish, and Betta tanks need a very slow flow rate. They can die of exhaustion, and it can cause unwanted stress for them to swim in the current all the time.
Threshold Sound Levels
Fish use their auditory sensitivities for various vital functions whether it is for attracting mates, scaring off predators and competition, or forming a social cohesion. Various researches have proved that fish are susceptible to noise pollution. Exposure to noise for a prolonged period can cause permanent hearing loss in certain fish, like goldfish.
So you should check for the sound levels of your powerhead to enhance the lifespan of your fish. If your powerhead is broken and making noise, repair it as soon as possible.
Type Of Aquarium
These aquariums are top-rated among hobbyists. The water temperature in these aquariums is close to room temperature i.e. 72 to 90 degrees Fahrenheit. You neither need any expensive chemicals to add in the aquarium nor any fancy equipment. If you are just starting in this hobby, this is the place to start.
These aquariums have an average temperature of less than 70 degrees Fahrenheit. The typical fish you can keep in cold water aquarium is goldfish. The other species are a little expensive.
These aquariums are built for the fish and corals of deep seas and oceans. You have to add salt in the water to make it sustainable for these fish. Marine fish are vulnerable to water conditions and require specific diets. Maintaining these aquariums is very expensive due to the corals.
This type of aquarium is the mixture of the freshwater and marine aquarium. You have to mix freshwater and saltwater. Fish are rare for the brackish aquarium, and the most common is the puffer. Very few people opt for this as the conditions are hard to maintain and the fish are not housed properly before they end up in your aquarium.
If you don’t want to be shocked at your electricity bill, make sure to check the power rating on your aquarium powerhead.

How Does An Aquarium Powerhead Works?
An aquarium powerhead is nothing but a water pump that takes water from one side and outputs it to the other side. Powerhead’s motor is usually sealed in a plastic case that makes it fully submersible in water.
The way you place your aquarium powerhead in the aquarium also plays a big role in how well it circulates the water in your aquarium.
Where Should You Put The Powerhead In An Aquarium?
This question must have popped up in your mind so that you can utilize the aquarium powerhead to the fullest. The most vulnerable spots in your freshwater aquarium are the corners because the debris gets stuck behind the plants or decorations. So you can aim your powerhead toward the corners.
The aquatic plants need carbon dioxide to survive; they fulfill this need by absorbing carbon dioxide from the gently flowing water. If the water remains still, a stagnant layer forms over the leaves, this hinders the stomata of the plants, and they eventually die. But if you position your high power powerhead right in the face of the plants they may bend and break.
Another factor is water turbulence at the surface. If water turbulence at the surface is high, it will drive carbon dioxide, and the rate of plant growth will decrease.
Fish in oceans are used to waves, so they need some more turbulence. So in a saltwater aquarium it is advisable to have a high power pump and if you have a large aquarium, use two powerheads instead of one.
An aquarium containing coral reefs and live rocks need a special kind of circulation. Live rocks have a porous surface that contains millions of bacteria that help in regulating the nitrogen cycle. Corals cannot move. So the water movement brings food to them. Water circulation also helps in cleaning the waste particles stuck on corals.
You can direct the pump’s circulation towards the corals but ensure it is not very high as the coral may free from the surface of high rock. If you are a purist, use a wavemaker to create waves intermittently instead of using constant flow.
