Water hardness determination using local laundry bar soaps for carp hatcheries
Share
Abstract
A simple method using local laundry soap is described for carp hatchery operation. A saturated soap solution was prepared and uses to titrate a 100-ml water sample of known hardness until a permanent lather appeared on the surface of the sample. The volume of soap solution was recorded to correspond to the hardness level tested. A fish farmer’s guide on the approximate levels of water hardness using WHEEL or PERLA soap solution is provided.
