ClayMend can be used around water features such as ponds with fish and other aquatic creatures. It contains naturally occurring organic acids that occur in soil including the soil around the water. The microbial population that ClayMend encourages is aerobic so any residual microbes that may result in the population expansion and end up in the water would perish from the anaerobic environment of the water. As always, exercise good judgment when applying ClayMend by reducing water flow of the applicator around the water feature so that the soil amendment gets into the soil where it is beneficial and over spray is at a minimum. We recommend keeping a border of a foot or two from the edge of the feature. Over time the microbes in those areas should migrate to the untreated border.
