Aquaponics @ Blue Lagoon (Koh Chang) – Tutorial/DIY

You can download our tutorial pdf to learn more about aquaponics (facts, & practical information) and how to start your own.

We weren’t planning on spending so much time at the Blue Lagoon Resort on koh Chang, Thailand, just a few weeks volunteering. And then the COVID19 lock down happened, we got stuck here… so we played Aquaponics! What can you do in this context that is more meaningful than developping systems for food resilience?

The system had been designed and built by Jo and his volunteers in February. Beautiful design built around fish tanks that had been here for a while. What a great way to improve something! But the bell siphons in the two flood tables didn’t function, so the whole system was stalled : no oxygen in the media beds meant bacterias couldn’t grow, nutrients werent being transformed, plants weren’t getting fed, and the water was accumulating ammoniac that would endanger the fish…

So we fixed it! We arranged the fish tanks to have higher density of fish (and droppings), installed a solid waster vertical filter (with drain valve), fixed both bell-siphons, twicked it here and there… and organized a workshop for volunteers of the DooDD Project and the Blue Lagoon’s team to understand the system, its potential, and how to maintain it.
