Microbe-Lift Calcium Montmorillonite - 2 lb.

It is said that the secret to Japanese healthy, colorful koi is the clay mud in which they are raised. This powdered clay comes from one of the highest calcium clay deposits in the world.

Plastic pre-formed ponds, as well as vinyl, cement and rubber ponds, do not have any nutrients on their bottoms. In the wild, carp actually use mud to get many of their micronutrients and minerals. This product has a negative electric charge, which will bind the clay particles to positively charged toxins in the water.

The clay acts as a natural flocculent and the particles that are bound up are filtered out of the pond. So the clay is not only a nutrient source for koi, it will also "polish" your pond water.

This material contains crystalline silica as quartz (CAS 1 4808-60-7). Crystalline silica in the respirable range is present at approximately 2% (Wt. %). The OSHA Permissible Exposure Limit (PEL) and the ACGIH Threshold Limit Value (TLV) concentration limit of 0.1 mg/m ^3 is not approached in normal product use (time weighted averages).

Use 1 level tsp. for 100-500 gals twice weekly.
Use 2 level tsp. for 501-1,000 gals twice weekly.
You may use more clay to meet your goals. Cannot be over-dosed.
