Ambush0908 Posted December 28, 2021 Share Posted December 28, 2021 Hello all, I have decided to get away from activated carbon in my planted tank. I am running FX6 filters. Right now I have the trays set up as the came. From top to bottom, bio foam, ceramic rings than carbon pads and bags I make up myself. I was going to add a filter pad and a polishing pad. Of course when you search the internet there is so much conflicting info I am not sure where to place what. Since the flow goes from top tray down I was going to go with a medium course filter pad on top with the polishing pad below it, than the bio foam in middle and rings on the bottom. I am considering the bio foam as biological so I didn’t think it should be on top. Bottom line is I am not sure would love any feedback from someone who has set up something similar. Thanks!

Administrators Zenzo Posted December 28, 2021 Administrators Share Posted December 28, 2021 When it comes to canister filters, I recommend having the first filter that water passes through to be a coarse material that will catch larger debris, then medium material or your biological media, with your fine filter pad/floss at the end. With the FX6, I believe that the water passes through the side foam pieces before going through the other media. Here is how I would setup your FX6: Coarse material on the outside ring (mechanical), medium foam on the top layer(s)(biological/some mechanical), bio rings in the middle (biological), fine filter pad at the bottom (polishing).

StevesFishTanks Posted December 28, 2021 Share Posted December 28, 2021 (edited) I have 2 fx4 and 1 fx5 running on 3 different tanks. On all of them I have the coarse sponge in the outside perimeter. I have each inside tray filled with 2 larger mesh bags of seachem matrix. I mix in crushed coral in a finer mesh bag in half of one of the trays. I use the canister as a massive biological filtration device. For mechanical I build foam prefilters out of parts from jehmco on the filter intakes. I service these with every water change and believe me they do their job. I open the canister once every 4 to 6 months just to make sure nothing is getting out of hand. It is usually in excellent condition. I had to saw my intake and use this Reducer fitting Edited December 28, 2021 by s1_ 1 Link to comment Share on other sites More sharing options...
Ambush0908 Posted December 28, 2021 Author Share Posted December 28, 2021 That is an interesting idea with the prefilter. I knew I would get some great ideas! Thanks for all the info on what is needed! Link to comment Share on other sites More sharing options...
Administrators Zenzo Posted December 29, 2021 Administrators Share Posted December 29, 2021 I also have a pre-filter on the intake of my FX4. Link to comment Share on other sites More sharing options...
