I was reading a post about canister filters and it was recomended not to use bio balls. I have a canister filter with one tray of ceramic noodles, one tray of bio balls and one tray with just a layer of white filter wool. Both trays of with the noodles and bio balls have a piece of course foam over the top. Should i ditch the bio balls and get something else or is this setup ok do you think, it is a 1200lt per hour canister and it is filtering my 6ft x 14 x 18 tank. I do weekly water changes but the water does get a slight yellowish tinge after about 3 to 4 days. Do you think this is not enough filtration or wrong media etc etc.
Sorry for the litres per hour im in Australia not familiar with gallons.
Any help or advice would be greatly appreciated quite new to this hobby
