Using EM•1® once per month will keep enough beneficial microbes in the system to keep nutrient levels low enough to improve overall water clarity. Interestingly, EM•1® also has the ability to neutralize salts, such as calcium, and prevent them from crystallizing on surfaces, a great benefit with water fountains using hard water. It will also clean the crystallized salts off the surfaces it comes in contact with.
On average, for a healthy pond or water garden, EM•1® Microbial Inoculant is applied once per month. The rate is 1 part EM•1® for every 10,000 parts water. Allow several weeks to a couple months for the EM•1® to work. Some slime (muck) from the bottom will slowly rise to the surface. Leave it and let nature do its thing as it will disappear shortly.
This chart is a quick reference guide to figure how much EM•1® you may need.

Higher concentrations are only necessary under extreme conditions where sludge and much are choking out the pond. When the pond resembles a wastewater lagoon more than a pond, apply at the suggested rates every other week until the water clears. Once the water clears, reduce application rates to once per month for maintenance.
