Testing the water in the aquaponics system

No matter how well balanced you think your aquaponics system might be, you need to periodically test the water to avoid any rude shocks. Here's how I did mine. My mate Rob also pointed out that it would be better to use phosphoric acid to reduce the ph rather than the tropical fish ph regulator that I used. Here's what the website says about phosphoric acid: "Phosphoric acid is made from the mineral phosphorus, which is found naturally in the body. It works with calcium to form strong bones and teeth. It also helps support kidney function and the way your body uses and stores energy. Phosphorus helps your muscles recover after a hard workout. The mineral plays a major role in the body’s growth and is even needed to produce DNA and RNA, the genetic codes of living things." Good call Rob!
