Microbe-Lift Calcium Montmorillonite Clay is 100% natural and specially formulated for pond clarity & koi health, growth & color. It is said the secret to Japanese healthy, colorful koi is the clay mud in which they are raised. Microbe-Lift Calcium Montmorillonite Clay comes from one of the highest calcium clay deposits in the world. Calcium based clay may actually help your pond's water to produce some of the healthiest and deep colored koi you've ever raised (or seen). The koi's marking will become brighter and more dominant. Plastic pre-formed ponds, as well as vinyl, cement and rubber ponds, do not have any nutrients on their bottom. In the wild, carp actually use mud to get many of their micronutrients and minerals. Microbe-lift Calcium Montimorillonite Clay has a negative electric charge which will bind the clay particles to positively charges toxins in the water. The clay acts as a natural flocculent and the particles that are bound up are filtered out of the pond. Microbe-Lift Calcium Montmorillonite Clay is not only a nutrient source for koi, it will also :polish" your pond water. The clay can actually help make pond water sparkling clean (polishing). The temperature band for koi is 62 degrees F-84 degrees F. At 50 degrees F, it will take about a week for koi to digest food. At 45 degrees digestion stops. At 60 degrees it takes about a day, at 70 degrees, food will pass thru in 2 hours. At 70-75 degrees, koi will have twice the time to digest their food if clay is added in sufficient quantities!
