I have a 46 gal bow front FOWLR. Right now im running a magnum 350 canister filter with the pro 60 bio wheels. I want to change that filter to a wet/dry trickle filter in a 20 gal sump. How should I go about changing out the filters? Should let both filters run on the tank for about a month so the bacteria can build up on the bio balls of the new filter? Any advice would be helpful.
