I just joined the site and have to say I wish I found it before I started my system (YouTube alone is hard to navigate although it did get me started). I have always been a soil gardener and am getting older now and was looking for an easier way to grow veggies. Aquaponics has sparked my interest so I decided to give it a try. Unfortunately, I may not have a big enough system to be stable enough to work.
The sump/fish tank is only a 32 gallon plastic trash can buried about 8 inches deep in the ground with dirt packed around it. I was hoping this would help cool it during the summer months. The grow bed is a kiddie pool with 4.75 cubic feet of river rock bought at Lowe's, about 7 inches deep.
