hey Tony. it is powered by a 1200LPH cheap power-head with a piece of hose jammed in the end. it fit perfectly believe it or not just had to pressure fit!. the carbon was from a bulk carbon supplier in Brisbane. they don't sell small amounts to the public tho as far as i am aware. Darren at reef secrets sells it! give him a call.i matt, how are ya?
just a quick one mate, what type of carbon are you running in your reactor, and what pump you got running it. It looks like it is just plumbed out and then back in of your return section, is that right?;)
