are you leaning that rock against the glass? aren't you afraid of scratching it up?
the mods i did to my biocube were really quite simple. removed the bioballs and replaced with LR rubble (roughly ping pong ball sized), removed stock filter pad and replaced with a sock with a bit of carbon, and widen (not deepen!) the overflow between chamber 1 and 2.
i may replace the stock pump with an MJ 900, but im still sittin on the fence for that one.
is that you heater on the right side? why dont you throw that into one of the back chambers? mine fits inside chamber 1 with the sock of carbon.
