WyldFya;793189; said:AC110's are still a mech filter. Same with the FX5. I would get one good mech filter, and one good bio filter. Eheims pro 3's and pro 3e's are both great bio filters. FX5's are great mech filters, but are very energy inefficient, and heavy. I'd run dual AC110s and a pro 3 or pro 3e. If you want to go cheaper, an eheim pro 2 2028 and AC110s would also do well.
O I'm sorry about that I thought that Aquaclears were good for Bio filtraion
