Aquaponics Update August 2012

Latest update of my aquaponics system during first 7 days of Raya. The ph and ammonia is so high. Maybe it is due to the alkaline condition of the media caused the ineffective nitrification process. Anyway, the ph is around 7.6 and the ammonia level around 1.0ppm.

From my observation, the watercress are doing very well in this kind of growing techniques. The water level is constant with continuous flowing rate at small volume on each grow bed.

My Latest Aquaponics System

It has been so long since my last post.  Anyway, this is my latest aquaponic system, built on last June- July 2012. These pictures was sent by my brother in Sabah.

I am still experimenting the best possible and simplest system. One thing for in my opinion, every aquaponic system should have some filtration system, regardless of the techniques used (media bed, deep water culture, nutrient rich technique and whatever), filtration system is really crucial.

In this system, the water level is constant, and I think, some adjustment should be done. The media is quite alkaline, around ph 7.5 to 8. However my mom said the fishes are great and healthy.
