This is a quick update on the catfish and the plants that are sprouting in the aquarium. This update is in anticipation of the addition of an NFT setup. In this video I do a quick brush over of how aquaponics works in regards to ammonia, nitrite, and nitrates. I show some plants that I am trying to re-sprout and I go over my plan to build an NFT system (nutrient film technique) in the dining room.
