Community First a nonprofit that uses Aquaponics to grow food

Pierre Mainguy started Community First when he was 23 years old as a way to help rural communities in Cambodia get access to clean water and nutrient-rich fruits and vegetables. With the help of rotarians and researchers, Mainguy built an aquaponics farm in the village of Sen Sok about 13 kilometers (8 miles) from Cambodia's capital, Phnom Penh. In addition to the farm in Cambodia, Pierre has a Community First outpost at The Huntington Ranch Garden. Mainguy and his partner, Brianne Zehm, educate visitors on the benefits of using aquaponics as sustainable way to grow food without wasting water.

Brianne Zehm cleans out debris from the fish tank.

Community First uses a one-pump system powered by solar panels at the Ranch Garden. It's a closed-loop system that filters water from the plant beds down into a sump tank underneath. That water is then recycled back into the fish tank where the process repeats without any water run-off.

"The name of the game in aquaponics is cultivating bacterium and crashing down the PH as low as you can." -Pierre Mainguy
Hydroton house bacteria that transform ammonia waste from the fish tank into nutrients for the plants, fruits and vegetables.
