Aquariums require a variety of tools to keep the water clean and flowing. One of the tools that you can utilize is a powerhead. Powerheads rests under the surface and circulate the water around the tank. This current produced by powerheads helps simulate natural conditions for fish or corals.
In our detailed article, we will discuss the benefits of using powerhead and how to set them up around your tank for optimal results. In addition, we will walk through detailed reviews of the top six best powerheads on the market to help you make an informed buying decision!
Why Should I Use A Powerhead In My Aquarium?
Powerheads are used in aquariums to get water flowing. This is extremely beneficial for a variety of reasons. Most importantly, powerheads help simulate a natural current. Currents help aerate water, transport food for corals, and keep consistency throughout the tank.
Powerheads also help to prevent water from becoming stagnant. If water is constantly moving, at no point is the water a different temperature or allowing debris to settle down. This is especially important for larger tanks where a lot of water is sitting still. You can use a powerhead to circulate water from a heater to help disperse it too. This way, the water will stay at a constant temperature instead of just warming up right next to the heater.
Some low-quality powerheads are missing essential safety components and that leads some experts to not recommend them. You want to purchase quality powerheads that are in a sealed container and have a grounding wire so that your fish are kept safe from stray electricity. Also, it is important to use a powerhead that doesn’t produce too much heat.
How Should I Position The Powerhead?
For a small aquarium, you can use one powerhead at an end of the aquarium to create a current like a river. A lot of experts recommend that you create a flow of at least 6 tank rotations per hour. 10 rotations of the water in the tank per hour used to be standard but experts are starting to say that a rotation of up to 20 times per hour is even better. Alternatively, you can also use two powerheads in a tank, one at either end that create a wave like pattern of water flow in the tank.
Medium tanks should use a powerhead at various points of the tank to help encourage the flow. Two or more powerheads should be used in medium tanks. For two heads, position them at opposite ends. At three, position them in opposing positions. For four, you can place one in each corner.
For tanks that are larger you want to use enough powerheads to get water flowing around the tank. Also, watching fish behavior is one way to discover what the proper amount of powerheads is.
What Are The Benefits Of Using A Powerhead?
Powerheads bring with them a lot of benefits. We have already mentioned a few of them but we are going to break down more of them for you here:
- Constant water flow
- Equalizing temperature across the tank
- Many fish like flowing water, especially saltwater fish and corals
- Oxygen is carried around the tank more efficiently
