Product Description
Forward or reverse flow for increased undergravel filter efficiency for aquariums up to 75 gallons. The unique reverse flow feature allows the power head to force water down the undergravel riser stem and beneath the gravel. The water flow through the gravel is reversed, promoting bacterial growth at the bottom of the gravel layer as well as the top. Easy to use slide controls effortlessly control both output direction and rate. Aqua Clear 802's impressive list of features has been carefully selected for long, durable service life, trouble-free installation and operation with minimum service required maintenance. The impeller housing swivels to adapt to most riser stem placements and the unit can be secured with either the convenient rim clamp or the suction cup bracket for submersed operation. Free floating impeller automatically self-aligns with pump coil for reduced friction and extended impeller life. Water movement switch is a superb feature--when slide shows green, the unit is pumping normally, when the indicator is red, the flow is reversed. 400 gph for aquariums up to 75 gallons. Output (with air) 22 l/min. Output (without air) 25 l/min. Power consumption per hour (120V) 20 W. Amperes per hour (120V) 0.22 A. In Reverse Flow: Output 11 l/min. Power consumption per hour (120V) 17 W. Amperes per hour (120V) 0.21 A.

 good stuff January 9, 2007
these heads are very nice, the price from amazon was hard to beat. Very powerful currents the reverse flow could be a little stronger but i guess if it was it would suck up all my fish =)
 Powerhead August 24, 2006
Powerful,compact unit.. Reverse and forward switches making this unit wonderful for enhancing beneficial bacteria in your aquarium.. Only problem I have found is its difficult to use the forward and backward switch, while in the aquarium and the switches sometimes break off
A MUST-HAVE for aquariums December 29, 2005

This powerhead is a great thing to have for your aquarium if the tank is between 55-90 gallons. It really packs a punch for its size, and has the capacity to move a lot of water fairly quickly. It can also be used in smaller aquariums too, because the waterflow on this powerhead is ADJUSTABLE (a feature that is rarely seen on other powerheads) - it can filter 300 g.p.h. or adjusted to filter only a trickle. So this can be a used in aquariums under 55 gallons too.
This also has another unique feature - a REVERSE-FLOW option - so the powerhead can also take water from close to the surface and move it through the gravel in the opposite direction. Whichever method of gravel filtration you prefer, this powerhead can accommodate you.
It comes with tubes that provide for the option of additional airation through the spout. So if you have a big aquarium loaded with oxygen hungry fish, these powerheads can provide lots of water surface agitation, water airation with bubbles, or you can just omit the bubbles entirely and stick with undergravel filtration only.
You can also buy attachable power filters to this separately - no need to invest in expensive poewr filters and powerheads separately - just buy this item and the attachable power filters and you're set for a powerhead / power filter in the same unit to clean up and polish your aquarium water. Look for the AQUA CLEAR Large Quick Filter and the Large Quick Filter Cartidges for this purpose.
I've been involved with aquariums for over 16 years, and this is one of the finest accessories for an aquarium I've ever had. If you're considering ornamental fish as a hobby, I heartily recommend this powerhead. It is powerful, quiet, and gives your options of reverse flow and adjustable waterflow.
Be advised on one thing - when the powerhead is operating in reverse flow, small fins like guppies can get stuck to the plastic grid from which water flows into the powerehead - and never escape. So this item is better suited to larger fish when using the reverse flow feature. But it's adjustability enables you to slow the waterflow to a trickle for a powerhead that does not promote too much water turbulation for smaller fish.
