FLuval 404 canister filters,running with beneficial bacteria

[kdblove_99]

Hey i was going to buy these are they normal filters? Just wanted to make sure this is the same ones if were to go to Big als? I'm pretty new at this. Beneficial bacteria? anything to worry about?



i have 2 of these that are currently running on my 360 that i will not need any more . if somebody has an empty tank they want to start up you can add these 2 and you would have an extremely fast cycling of the tank without loss of fish 75 dollars each or 120 for both.

im assuming you're buying this filter used.

Yes they are used! What do you think? I wrote what he put, So they are just normal Fluval 404 filters right? he almost makes it sound like they are just for starting a new tank?

Sounds like they are normal 404's and that they've been in use for a while so they have already built up the beneficial bacteria that would be helpful in starting a new tank.
