Estes Stoney River Aquarium Substrate; Beige

Stoney River Premium Substrate is a high-quality Silica Sand or Gravel ideal for aquariums, terrariums, crafts and planters. Because it is composed of Silica, our substrate will not buffer PH so it is suitable for both freshwater and marine environments. Some items include a durable, non toxic polymer coating to enhance it’s appearance.

Aquarium Use: For optimal decorative effect use 1.5 to 2 lbs. of substrate per gallon of aquarium capacity, or 180 to 240 grams of substrate per liter of aquarium capacity.

Available Size: 5 lbs (2.27 kg)
