Water Change In Aquaponics
In an aquaponic system like Nature Garden, the water would never need to be changed since ammonia would be neutralised and converted into nitrates for the plants to absorb.
All you would need to do is to top up the water once every 2-3 weeks due to plant absorption and evaporation. This is the reason why the water in Nature Garden always stays crystal clear.
Comparing to a normal aquarium tank where frequent cleaning and water change is required; aquaponics is far less maintenance.
