Do i really need my Marineland C360 canister? The only thing i have in it is about 3 lb of 1/4" porous rock and carbon. I was thinking of putting the rock in the back of my tank and the carbon in my PO3-4 reactor. I have a 60 gal with 20 lb of new sand and about 45-50 lb of rock, a eshopps psk-100h skimmer. I have 3 clowns, 1 long nose hawk fish and a purple fire fish. 2 nems, 2 brains, 3 acans, 1 frog spawn, zoes, toad stool lather, kenya tree and giant green tip shrooms. thanks
