So I just got a Biocube 14 and it was pretty much stock although it had a good amount of coraline on the back. Heres what I did to it.
I pulled out the stock pump and replaced it with a Maxijet 900. This really created a good amount of flow. It also allowed me to remove my extra in display pump. Freed up some great space!
I used the stock set up to create a media rack in chamber two. I pulled out all of the bioballs and under the grate that they sit on I put chemipure. I put chaeto in the middle chamber where the bio balls used to be and I used filter floss on the top of chamber two. Here are some really poor photos of it.
