So I have a 14 gallon biocube setup and I would like to use the middle chamber to build my tiered filtration system. I visited my local FS and they had these mesh paddings:

Ammonia
Carbon
Phosphate
Polyfiber
​

how should I layer it and what should I layer? keep in mind that it is 15" tall and 50% will be submerged. I can also set the egg crate levels at any height. Any and All advise will be very welcome!

Thanks ahead of time for the replies!
