Here is the design I drew up for my wet/dry to go on my 125. Let me know how it looks and/or any way I could change or improve it. The bioball/scrubbies chamber should be about 8 gallons.
The first filter sock part is this, http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3579+3587+16746&pcatid=16746, there would be 2 of them side by side (1 per overflow). Although I probably would just make something similar rather than buying that. Then on top of the bio media I would have a filter pad then a drip plate. I plan on using 2 mag7's for the pumps.
