I have a Via Aqua canister i will be setting up for my upcoming 55 lightly planted tank. What media to use? I have 3 baskets 1 fine pad, 1 coarse pad and 1 empty. Should i use bio balls, bio rings, pot scrubbers, lava rock in the 3rd basket? And how should i arrange the baskets for best filtration? I'm new to canisters
