Benefits of a Powerhead in a Freshwater Tank

Benefits of a Powerhead in a Freshwater Tank

 

Water Flow

One of the main reasons people add a powerhead to their freshwater tank is to increase the turnover rate. This can help reduce “dead spots” that your filter might not be powerful enough to reach. By reducing pockets of stagnant water you reduce the risk of harm befalling your fish, and adding a powerhead can also help increase the number of nitrifying bacteria in a freshwater tank.

 

Stimulate Fish

Another good reason to put a powerhead in a freshwater tank is to provide your fish with a more natural environment. A lot of fish we commonly keep in aquariums come from streams and rivers. In these moving bodies of water, they constantly have to swim against a current to seek out mates and to find prey. By adding a powerhead to an aquarium you can keep your fish active throughout the day, which can help bolster their overall mental and physical health.

 

Remove Debris

If you run your powerhead close to a gravel substrate it can help stir up some debris from the bottom of your tank. This debris can then float towards your filters intake, so it can more easily be removed from the tank. This can be especially helpful in planted tanks where you can’t easily use a gravel vacuum, or if you are just looking for an easy way to get some of that detritus out your tank.

 

Visual Effect

The current a powerhead generates also can add a nice amount of movement to your tank. Not only will your fish be more active, but your plants and other decorations will also respond to the water flow as well. Long leaf plants like Java Fern or Hornwort will react the most to a powerhead, but even small to medium plants like anubias will also move around in your tank.

 

 

 

What Size Powerhead Do I Need

What Size Powerhead Do I Need

If you plan on getting a powerhead for a freshwater aquarium then you will need a powerhead that has a flow rate of 10 GPH (gallons per hour) for every gallon of water in your tank. That means if you have a 20-gallon aquarium you will need a powerhead with a flow rate of 200 GPH in order to properly circulate your tank.

 

 

 

Aquarium Circulation Pump Placement Freshwater

The optimal powerhead placement in a freshwater tank is towards the top of your tank. This will create the most surface agitation, which will help oxygenate the water. Placing a powerhead higher in your tank will also limit the amount of debris the pump stirs up. Moreover, if you use a sand substrate, then you definitely want to keep the power head as high up as possible since you don’t want it to blow sand particles all over the place.
