left picture is how i use to fill my fx5
bio media in the middle and poly fil on the sides
whenever i notice water flow weak i would just throw away the dirty poly fil and replace with new
heard alot of people have good results running all bio in canisters so i decided to try running pond matrix in the middle and had some pot scrubbies and bio balls laying around so i filled the sides with them
anybody run their fx5 like this? how do you like it? how often to you have to open up the canisters and clean them?
