Healthy water is built on a good filter, regular water changes and, when needed, a few targeted products. A water conditioner neutralises the chlorine in tap water, bacteria start up and maintain the filter, clarifiers clump together the particles that cloud the water, and KH, GH and pH adjusters stabilise a pond whose water is too soft or unstable. Phosphate removers starve algae of their food.
Before any treatment, test the water with a test kit to find out what is wrong. In aquaponics, favour biological products and avoid anything that could harm the plants. The article Understanding and fixing cloudy water in aquaponics helps with diagnosis.
