Do you need a air pump to power this or do you plug it in to an outlet? And should i buy a 20 for my 20 gallon saltwater tank?

Answer by ChewyJun 25, 2018
This water pump needs to be plugged into an outlet. Size 20 is ideal for 5 to 20 gallon aquariums.

Will the aqua clear filter cartridge fit the 20 powerhead?

Answer by ChewyApr 04, 2024
The Powerhead filter is the AquaClear Quick Filter for Powerheads for Polishing Water. That product fits Powerhead Pump models 20, 30, 50 and 70.

Do you have to use the suction cups. Our aquarium is like a clam shell so can’t use suction cups. Would attaching to top be sufficient.

Answer by ChewyFeb 11, 2018
This water pump does not have to be used with the suction cups.

How strong is the water flow? I have a Betta and they do not like strong water flows. Even though you can regulate it, I want to be sure very little water comes out.

Answer by ChewyApr 22, 2018
This water pump is suitable for tropical freshwater and marine saltwater tanks. There is a slide lever around the bottom of the powerhead that opens and closes an opening to the inlet adjusting the flow rate.

Not fully adaptable

I wanted a super quiet powerhead for an under-gravel filter. This one is very quiet, but the only adaptor it comes with is to smooth and steep of an angle to work

I wanted a super quiet powerhead for an under-gravel filter. This one is very quiet, but the only adaptor it comes with is to smooth and steep of an angle to work well with a standard 7/8-inch id X 1-inch od uplift tube. It will have to be modified to work right with an under-gravel filter system.

Not making replacement media now.

Why is this even being sold when the replacement media is not available anymore?

Best powerhead I've used

This thing hasn't changed much in 20ish years. Pretty sure this is exactly the same thing I bought in high school. If it works, it works, I guess. Feels much stronger

This thing hasn't changed much in 20ish years. Pretty sure this is exactly the same thing I bought in high school. If it works, it works, I guess. Feels much stronger than competitors I have tried. I appreciate that it doesn't come with a bunch of extra flimsy plastic parts that I have no use for.

Open box...

Box is open and don't know if any parts are missing. I am trying to read the instruction to see. Very disappointed. I thought I was buying brand new pump.

Doesn’t hook up very easily

I bought to connect with a undergravel filter system. It didn’t hook up unless you pushed it nearly to the bottom of the tank. I tried to adjust the outflow but

I bought to connect with a undergravel filter system. It didn’t hook up unless you pushed it nearly to the bottom of the tank. I tried to adjust the outflow but the small adjustment dial doesn’t decrease the flow.
