Koi Bible Water Quality
Finally, a book on water quality and water composition (168 pages)! Until now, there has never been a complete book published on koi pond water management. A must-have for every serious koi keeper. After a well-received first book on identifying and assessing koi, Joop van Tol of KoiToday.nl is now releasing a second book called "Koi Bible: Water Quality."
Joop's second book is written on three levels: "Need to Know," which covers essential knowledge for successful koi keeping. "Nice to Know," which provides in-depth information and connects the dots to help you better understand the processes. Finally, "Nerd to Know," for the true diehards who want to know everything about their pond down to the atom. Each section is labeled green (basic), yellow (advanced), or red (nerd), allowing you to progress through the book at your own pace. The ratio is roughly 65% green , 25% yellow , and 10% red .
