Quiet freshwater and saltwater powerheads ideal for creating less noise in your tank.

Penguin® Power Heads deliver constant flow with fully adjustable aeration and increased surface agitation...and they remain silent at all times. The custom air valve regulates air flow, the air filter eliminates noise and dust, and the intake strainer keeps debris from fouling the impeller... that's efficiency!
Penguin Aquarium Power Heads is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Powerhead as a filter I bought the power head to use with my canister filter - but am keeping German Blue Rams which do not want a high water current. So I used just the power head and put a $1 car wash sponge (new in package) onto the intake and it is the best aerator and filter I have in my100 gallon tank as the power heads are cost efficient in general.

I want to use an underground filter in a 120 gallon XH with African Cichlids. What size power heads should I purchase and how many?

Asked by: Marlowe
I'm not sure I would recommend a UGF for a number of reasons, but if you do decide to go that route, I would use at least 3 or 4, and probably the Penguin 660.BREX

Got a penguin 550 powerhead. Comes with an "air valve with Aerator/Air Tube". Does the air valve go inside or outside the tank. I know the airtube connects under water 2the Impeller Housing, but I need 2know if the otherends goes inside or outside tank

Asked by: Rbtt
It has to be outside the tank in order to pull air into it.BREX

The lift tube on the 1140 is smooth unlike the others. Will the 1140 still work with an under gravel filter?

Asked by: jthall07
Yes, it is definitely for undergravel filters, although a bit powerful for them.BREX

undecided which size I should purchase - I have a 90 gallon and want 2 to power my undergravel filter - think 2 of the 660's would work well - am going to to raise angel fish and have some tetras schooling around as well -

Asked by: Maxxim
The 660s should work well. You wouldn't want any larger because the kind of fish you are planning on keeping would get blown around a bit.BREX

Snubber circuit to protect relay controlling 550 and 660 powerhead

I am constructing a digital timer to control 550 and 660 powerheads. I want to connect a snubber circuit across the relay contacts to protect them from the inductive spike triggered by the pump motor upon turn-off. Can you recommend resistor & capacitor component values for this job, or alternatively propose a ready-made snubber device. Failing that, I need the resistance and inductance of the 550 and 660 powerhead motors.Thank you.
Asked by: julianop
From our engineer:I do not have any suggestion for the values needed for a RC snubber.The DC resistance for both motors is about 170 ohm.The motor inductance is unknown.My suggestion to the customer would be to pick nominal RC values and try to witness the contact in a dark room.That is assuming that the case of the relay has the contacts visible.The value of the RC components can then be altered to minimize the apparent spark on opening.Otherwise try an electronic relay or our Wave maker power strip.BREX

Penguin aquarium powerheads

I am interested in getting a penguin powerhead. Which one would be the best for a 75 gallon aquarium. Can the flow be adjusted? Thank you.
Asked by: bulldog51
That depends on what you wish to do with it, but most likely the Penguin 1140 would be the best one if you wish to circulate water from one end of the tank to the other.BREX

Penquin 1140

On your website, you show a picture of the Penquin 1140 along with the 550, 660 and 550R. But when I go to order, the only options are the 550 or 660. Do you no longer make the 1140, and if not, why is it still on your website?
Asked by: Alchemist
We do make the 1140. If it is not an option currently, then it is out of stock at the moment. As of next week, however, we will no longer be selling anything other than parts and media on the site.BREX

In 2001 I bought an Eclipse System - The pump is dying. I need a replacement.

I believe it was a system 6
