Add a splash of color to your tank with this striking, bright, and colorful Pure Water Pebbles® Red Aquarium Gravel, 5 lb Coated Pebbles substrate.
This natural gravel substrate is coated with colorfast, nontoxic acrylic that won't alter the chemistry of aquarium water.
In addition to the increase in visual interest, gravel substrate helps your aquarium's ecosystem by increasing surface area for the colonization of beneficial nitrifying bacteria. Substrate is also great for anchoring plants or other decor.
Directions for use:
Rinsing prior to use to remove dust is recommended. For best results, use approximately 1.5 lb of gravel per gallon of aquarium water
