Kai Zen Aqua
The Japanese definition of "kaizen" is "continuing improvement", and this forms the basis of our own philosophy in developing effective medications for sick fish, as well as water treatments to maintain a healthy pond environment. In over 25 years of experience as koi and pond hobbyists, we were never able to find any medications of sufficient strength or quality to success fully treat ailing koi. Looking through the microscope would show that the meds didn't work, so continuing to buy these products proved to be a huge waste of time and money.
KaiZen is the result of extensive research using lab grade medications in dosages which have been proven effective. Extensive travel in Europe, Israel and Japan also helped with research into what medications and treatments have a proven track record in other countries.
