Aquaponics Biofilter
Kennie D’s homemade biofilter for the Aquaponics system described in this post. Two videos here, one biofilter without aeration tube and one with aeration. Also, very cool explanation about the chemistry involved in turning ammonia (from fish excretions) to nitrites and then to nitrates for the plants. This one has no aeration. This one has

Aquaponics System
Kennie D. shows us how he built an experimental, indoor aquaponics system for testing plant growth. If you want more information, comment below and Kennie D. will get back to you. Some misc. notes: See this post on home-made biofilter. White “tanks” where plants are resting are actually 4 x 4″ plastic fence posts
