This is an excerpt from this article from the University of Florida, Institute of Food and Agricultural Sciences (UF/IFAS) This document is FA37, one of a series of the Fisheries and Aquatic Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Original publication date June, 1997. Reviewed July, 2002. Visit the EDIS Web Site at http://edis.ifas.ufl.edu., and supplies the easiest way to dose pp:

Use of a Stock Solution

An alternative method of measuring potassium permanganate is to mix a stock solution. A stock solution is a concentrated solution of chemical from which small amounts can be taken to treat tanks as needed. This is useful when either multiple tanks or multiple treatments are needed. An easy way to make up a stock solution for potassium permanganate is to purchase a one-gallon bottle of distilled water, weigh 285 grams of potassium permanganate, add it to the solution, and mix thoroughly. This stock solution will deliver a dose of 1 mg/L when delivered at a rate of one drop per gallon. Therefore, to achieve the desired concentration of 2 mg/L, the stock solution can be delivered at a rate of two drops per gallon. The stock solution should be stored in a cool, dark area and be replaced annually.

I hope this helps :)
