I'm the process of getting ready for my rescape and cleaned out my Eheim Ecco 2234. According the the instructions for the order in which media should be arranged from bottom to top is: coarse blue media> Substrat Pro> fine white media (or carbon pad).
I got to thinking, wouldn't it make more sense if the media was this way instead? coarse media>fine media>biologic filter>optional carbon pad. As water enters the mechanical media, large/small particulates get trapped, so that the Substrat Pro would be less likely to clog over time.
Looking around the web I found that ADA Japan has the same concept for their high end Super Jet filters http://www.adana.co.jp/aj_web/na/basics/basics_04.html
Has anyone ever tried this arrangement?
