Water Garden premium natural gravel is un-coated – colors will darken and be enhanced once the gravel is wet.
Designed specifically for use in freshwater aquariums, this gravel is non-toxic and inert, and will not affect water chemistry in any way. This natural gravel provides the required surface area and spaces between individual pebbles for beneficial bacteria to colonize.
HOW TO PREPARE YOUR GRAVEL: Place the gravel in a clean strainer or colander. Hold the gravel under running warm water for several minutes until the water runs clear. This will rinse away and surface dust or debris. For best results, shift and move the gravel to help stir it up as it is being rinsed.
