hmm looks pretty good cept i still tink the filter floss and scrubbers are in the wrong place cuz the scrubbers will probly hold most of the larger particles, making the floss kinda useless. hmm thats one beef
the other is the 3 chamber and how the flow get to it, see if media is placed in there, the water is not forced to pass through it, it probly be more effective if could rise up and over flow to the chamber with the rio pump.
Sory if im seeming harsch but jsut my perspective on this, tryin to help to the best of my knowledge.
