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.
