I've been looking at some popular powerhead. I really like these Aquaclear powerheads because you can add a little filter cartridge into it. Do any of these have their own built in air pumps? I see the little air tube coming off the aquaclear powerhead, does that mean it needs to be hooked up to an external air pump? Basically, are their any powerful powerheads that come with their own internal air supply?
