The AquaClear 50 powerhead has a maximum flow rate of 270 gallons per hour, with a reverse flow option. It is designed to improve water circulation, and with an optional filter cartridge attachment, improve mechanical filtration.

Out of the box, the Aquaclear 50 powerhead comes with two different aquarium attachments: an aquarium rim attachment and internal suction cup attachment. I use the rim attachment to hold the clear plastic aeration hose, while I use the suction cup attachment to suspend the powerhead a few inches beneath the waterline.

The aeration hose draws air into the outlet stream, pushing bubbles into the current. There is a simple regulator placed at the end of the hose to adjust or even stop air flow.

The pump can operate in two directions. There is a normal flow, and reverse flow switch marked in green and red. Normal flow is used for pumping water parallel to the waterline. Reverse flow pushes water down towards the gravel, useful for undergravel filters.

Of important note is that in reverse flow mode, the intake valve is a narrow tube; it may suck up and trap small fish inside. It is best to plug the intake valve with a sponge material to prevent any accidents. However, under normal flow, this is not an issue, as there are no tubes under the intake.

I purchased the AquaClear 50 powerhead on Amazon with an AquaClear filter attachment and filter cartridges for my 55 gallon African cichlid aquarium. I originally intended to use the powerhead to circulate and aerate my aquarium.

Aquaclear Powerhead 50 polishes water during cleaning.

However, I have a tank divider in the aquarium to protect fry. The result is that the flow from the powerhead is confined to one side of the divider. I find the powerhead too strong for either division.

There is an option to turn down the flow from the powerhead, but I find the difference negligible. I believe for a divided 55 gallon tank, the AquaClear 30 powerhead or AquaClear 20 powerhead would be a better option.

AquaClear Powerhead with filter assembly and cartridge. Great for polishing water

I still use the AquaClear 50 with filter attachment and cartridges to polish the water when floating debris builds up or when I clean the tank. I find it works perfect when I vacuum the gravel, as it picks up all the churned up debris.

Overall, I am happy with this powerhead. I believe it should have a wider range of adjustment on the flow regulator, then I could use it in my divided tank. Despite this shortcoming, it performs as advertised.

Here is a link for other AquaClear powerheads of the same product line, with different gallon per hour output.

  1. AquaClear Powerhead 10 – 110 V, 80 Gallons per Hour
  2. AquaClear Powerhead 20 – 110 V, 127 Gallons per Hour
  3. AquaClear Powerhead 30 – 110 V, 175 Gallons per Hour
  4. AquaClear 50 Powerhead, 270 Gallons per Hour
  5. AquaClear 70 Powerhead, 400 Gallons per Hour
  6. AquaClear 110 Powerhead, 900 Gallons per Hour. Read the reviews on Amazon for this intense powerhead before buying. The 110 powerhead can kill fish, the suction on the intake is so strong!

And finally, here is the link for the filter attachment and cartridges:
