What size tank?? Anything over a US 55g with gf I would really consider
using the Fluval 404... In my US 55g alone I am running a Aquaclear 300,
200, and 402 powerhead with cartridge for filtration...>>
My tank is only 30 gallons -- I've read that a 204 would be enough but I'd
rather have some over-filtering than risk not having enough.
>> Stay informed about: filters
