How much Bio filtration to put in my cannister
I have been researching old posts on what to put as media in my cannister - I'm replacing all media for my new setup. It'll be a 100 gallon low tech planted tank. The cannister has 3 trays. I'll have a prefilter sponge on the intake, and the top tray will be filter floss. The second and third trays are up for debate. Some of the old posts said it's not that necessary to have a lot of bio media in planted tanks, other opinions said you can never have too much. So. What would you recommend? A second tray of mech filtration - more floss or sponge of some type, with the ceramic noodles in the bottom, or should I fill the 2 lower trays with ceramic noodles or some other type of bio media? I'd appreciate some input. Thankyou!
P.S Is it worth replacing the ceramic noodles with bioballs, or are they both just as good as each other? I hear mixed reports on bioballs.
