I was thinking about getting a powerhead for some added current for my plecos in my 55 gallon tank. I had heard that it is also a good way to keep "junk" from congregating at the bottom of the tank (sand substrate). What is a good one to buy? How should I go about positioning it? Does it need an air pump to run?
Basically any and all info would be appreciated.
TIA

Any powerhead will do, generally the more expensive ones will have more features. The better ones can adjust the flow from high to low. They work with an impeller inside that sucks water from underneath them...and shoots it out like a gun. The tops will have a little hole where you can attach an airline tube. The other side of the airline tube is left out of the water, and instant bubbles in the flow!
Power heads are great for maximizing water air exchange and don't require a pump. Their position should be an inch or two from the waters surface. They can sit on a down tube or hang from a mount that they come with that hangs from the top of the tank.

An airpump is not required, unless you plan on positioning the power head at the bottom of the tank--some of the weaker power heads might not be strong enough to draw air in at that height.

Aquaclear 402 is a popular choice.

Hope this helps.
