WARNING
We intend and expect that people using the Guide and its Supplements will be intermediate to advanced Koi keepers, e.g., we expect you to know how to make a solution in parts per million. If you ever have any questions or doubts about the information or its presentation, please ask rather than take the chance of interpreting it wrong and maybe hurting yourself or your fish.
