Abstract
A kit and method are provided for determining the suitability of the level of organic material in an aquarium. A test sample of water is removed from an aquarium into a test sample container. The pH of the test sample can be lowered and then a quantity of potassium permanganate is added and the test sample is permitted to sit. A control sample of distilled water mixed with an equal amount of potassium permanganate is also prepared in a second container. After a period of time passes, the color of the test sample is compared to the color of the control sample. If the test sample is significantly lighter, additional potassium permanganate is added to the test sample and this procedure is repeated until the test sample achieves the color of the control solution. The amount of potassium permanganate needed to turn the test sample to the color of the control sample is directly proportional to the amount of organic material in the tank. If more than a specified amount is added, the level of organic material in the tank is too high and remedial measures are needed.
