Ponds

Depending on of the condition of the pond, you will need to give it several months to fully recover. You should also look at trying to find the source of the nutrients going into the pond which are causing algae growth or slime and try to stop it if you can to prevent this from happening again.

A general starting point is to apply EM•1® at a rate of 1:10,000 on a monthly basis (100 gallons per acre foot) if the pond is in poor condition. If it is in very poor condition, the application is done twice per month until desired clarity it achieved.

In systems that have high flow rates or excessive sludge levels, the addition of EM•1® Bokashi can accelerate sludge digestion.

Calculating the amount of water in the pond:
Taking an average of the volume of the pond to calculate how much EM•1® Waste Treatment you will need is fine. If it is a small pond, say 300 gallons, figure your numbers by using ounces instead of gallons. Follow the application chart on this page to find out how much EM•1® Waste Treatment you will need.

The live microbes in the EM•1
® will work on breaking down lignin, carbohydrates, cellulose and other starches in the wastewater sludge. Laboratory analysis has demonstrated these effects.

This is evidenced by a reduction of BOD, COD, and sludge levels. It can also be measured with a secci disk.
