Microbe Lift's Calcium Montmorillonite Clay has many uses in the pond including:

  • Improved fish nutrition through mineral ingestion
  • Improves fish color
  • Clarifies pond water through flocculation
  • Improves water quality through toxin absorption

It is said the secret to healthy, colorful, Japanese koi is the clay mud in which they are raised. Microbe-Lift CMC comes from one of the highest calcium clay deposits in the world. Calcium based clay may help your pond water to produce some of the healthiest and deep colored koi you've ever raised! The koi's markings may become brighter and more dominant.

Lined ponds, do not have any nutrients on their bottom. In the wild, carp use mud to get many of their micronutrients and minerals. Microbe-Lift Calcium Montmorillonite Clay has a negative electric charge which will bind the clay particles to positively charged toxins in the water. Microbe-Lift Calcium Montmorillonite Clay is not only a nutrient source for koi, it will also "polish" your pond water. The clay acts as a natural flocculent and the particles that are bound up are filtered out of the pond.

There are 2 ways to use CMC Clay in your pond.  First is to add directly to the water at rates in the table below.  Second is to add it directly to the fish food your fish are getting. 

To add to the fish food, dampen the food and add the clay to coat the fish food pellets.  Then spread out the food to dry before putting back into the food container.
