As with anything, too much can create a toxic situation. The proper use of rock and gravel in a pond is actually quite beneficial. It creates more surface area for nitrifying bacteria to grow. It creates more surface area for periphyton to grow and thrive augmenting the Oxygen content of the water and creating habitat for myriad micro-organisms to also grow and thrive increasing the biological diversity of the pond's eco-system. In doing so creates the predation level needed to keep many aquatic pathogenic organisms in check. Enables, with proper husbandry, the pond's eco-system to achieve a biochemical balance not found in a liner only pond.
