biofilter



 
This is the "bio-filter" to my aquaponics experiment. It's made from a plastic filing box, and it's filled with red lava rock. Red lava rock is the most recommended growth medium, because of all the nooks and crannies each piece sports. This year, I've chosen to grow strawberries in it.
