DIY water testing kits are handy equipment that allow people to evaluate the quality of their water at home. When assessing the quality of water for numerous applications, including drinking water, aquariums, and gardening, pH—which measures the acidity or alkalinity of the water—is a crucial consideration. Water filtration media called GreensandPlus Water Filtration is used to eliminate hydrogen sulfide, iron, and manganese from water. It is an enhanced form of the conventional greensand, glauconite, a naturally occurring mineral that has long been used to cleanse water. One gas that can give water a rotten egg scent is hydrogen sulfide. Hydrogen sulfide in water can be oxidized and eliminated with the use of Greensand Plus.
