I'm currently running the Sun Sun HW 704b canister filter on my 115-gallon tank. I was thinking about buying an additional filter to add with the Sun Sun but My wife bought me a gift FX4 canister that does 250 gallons.
Do you think the fx4 is an upgrade?
If so what's the best way to switch filters Without shocking my tank.
