For over forty years, Estes has been the top manufacturer of aquarium aggregates in America. Their Permaglo Gravel is a great choice for aquariums, terrariums, and planters. It comes in a 5-pound bag with a beautiful rainbow color. The gravel is standard-sized with bright, colorfast hues. It's completely non-toxic, making it safe for all aquatic environments, including marine and terrarium tanks.

Using this Estes Permaglo Gravel is easy. First, rinse the gravel thoroughly under running water to remove any dust or debris. Then, add it to your aquarium, terrarium, or planter. You can spread it evenly to create a nice base. When it comes to maintenance, occasionally stir the gravel to prevent waste buildup. If you notice any discoloration or debris over time, you can remove the gravel and rinse it again. Remember, this gravel is non-toxic, but always keep it out of reach of small children who might put it in their mouths.
