Im seting up a 40 gal I have both filters the 3000 will be stock but the 30-60 will have 2 refillable trays full of eheim pro bio so whitch filter should I use. The tank will house 1 fw cichlid at 9 inchs for about 6 months only.
i hooked both up to a established tank im really likeing the 3000 it has more flow and a air feature does any body else use these HOB filters and how do you like these two. my empereor 400 has been been running for over 10 yrs now.
