Fountains, Small Ponds with goldfish and koi: Treat only those fountains and ponds which will have no outflow after treatment. High water temperatures cause more rapid natural decay of dead algae which can cause fish distress. Instructions:For best results, use at least one pound of sand per gallon of water. For deep sand beds, use at least two pounds per gallon of water. Rinse a few pounds of sand at a time until water runs clear. Never use soap or detergent, as they may harm fish. Place the rinsed sand into the aquarium. Placing a new substrate directly over an established bed can harm aquatic life. For an existing aquarium, gently mix small amounts into the established substrate over a period of a few days.
