"Recirculating systems are mechanically sophisticated and biologically complex. Component failures, poor water quality, stress, diseases, and off-flavor are common problems in poorly managed recirculating systems" (Masser, et al., 1999, p. 1).
This module's focus is water quality. As an aquaponics operator, you "must have a good understanding of water quality chemistry, be able to accurately use meters and chemical test kits, and take the proper actions to quickly correct problems" (Damron, 2013, p. 502).
In this micro-course, you will
- complete readings and exercises that will allow you to outline the nitrogen cycle and explain its importance to basic aquaponics function;
- monitor and maintain aquaponic water quality for important characteristics such as pH, oxygen, conductivity and ammonia;
- supplement with micronutrients to maintain nutrients such as iron, potassium and/or calcium when or if required; and
- identify the basic kits and meters available to measure water quality.
You'll also complete a quiz at the end of the module to gauge your understanding of the module's content.
- Determine which, when, and where water quality parameters need to be monitored in aquaponics systems
- Identify and select appropriate methods, kits, and meters that can be used to measure water quality
- Interpret water chemistry and relate it to aquaponics system function
