Build a powerful fish tank heater for your aquaponics or aquaculture fish tanks with easy to get, inexpensive parts. My plan is to build a solar heater to maintain tank temperatures during the day and use this electric heater will take up the slack at night.

Notes:
1. I forgot to mention in the video that the FMC (flexible metal conduit) is temporary and I am changing it today. I opted to use a heavy gauge outdoor extension cord.
2. The temperature controller can be purchased here http://www.amazon.com/gp/product/B008KVCPH2/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B008KVCPH2&linkCode=as2&tag=dtpaquaponics-20. It will require the use of a contactor that can handle the wattage of whatever element you use.
3. I found a contactor that has a 30 amp contactor rating and a 120 volt coil for around $5.00!! It can be purchased here http://www.amazon.com/gp/product/B001KGSJ74/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B001KGSJ74&linkCode=as2&tag=dtpaquaponics-20
