Koi Keepers enrolling in this course will become familiar with:

• The need to maintain great Water Quality for the health and welfare of the Koi
• What affects Water Quality
• The chemical makeup of Koi pond water
• The pond nitrification cycle
• How to test and correct:
  • Ammonia
  • pH
  • Nitrite
  • Nitrate
  • KH or Total Alkalinity
  • GH or Hardness
  • Dissolved Oxygen
  • Salinity
  • Chlorine/Chloramine
• Green Water
• Testing to prevent disasters
• Why clear water is not necessarily quality water

All students will need to own drop type test kits and/or meters for testing Ammonia, pH, Nitrite, Nitrate, KH, and Salinity.
All students will need an email address, the ability to send and receive files by email,  and internet access to the K.O.I. website.

At a minimum, it is recommended that students have reviewed and understand the information presented in the K.O.I. 101 course, available free on this web site to Registered Users. This is an intermediate-level course, and will require some math skills.  K.O.I. offers #500-Applied Math for Koi, which you may want to take before or concurrently with this course if the math is a problem.

Water Quality is probably the single, most important aspect to grasp in order to become a keeper of healthy and prospering Koi. The purpose of this course is to instruct the student on how to acquire quality water, how to perform proper testing, how to understand test results, and how to properly react to test results. The student will learn that water quality and water clarity aren’t the same; crystal clear water can contain compounds that are deadly to Koi.
