Ok, I got a cascade 1000 and put it together tonight. I dont have it up and running yet (hopefully tomorrow), but I put the baskets inside. It only came with three sponge things, one thick black one and a carbon bag. Someone suggested getting bio filter, so I got some of that and it didnt come in a bag like the carbon. On the bottom basket, I put a sponge, the black sponge and as much bio-filter I could fit in there(no bag). The second basket I put the carbon with a sponge, and the third just had a sponge. Did I do this right, or is there something else? What other media should I get in there? Thanks for your help, I will provide pics tomorrow!
