Hi, I will be putting a canister filter on my setup and currently am unsure of what to put in it and perhaps it isn't even a good idea to use a canister filter. I will be using live sand and rock in the tank. Should I put bio balls in the canister filter to help with biological filtration or not. I will be putting in a couple sponges for mechanical filtration and carbon for chemical filtration but am curious if it is a good idea to use bio-balls in there as well for added biological filtration. Thank you
