Lace Rock Natural Stone Aquarium Kit - 36" x 10"

This lace rock display is large, and it will span the length of a 55-gallon tank, leaving 4 inches of space on both sides. On a flat, hard surface, it measures 11" high, so if your aquarium has a healthy amount of substrate, you will want to factor that in to make sure it isn't too tall for your project.  These lace rocks will raise the pH level in your aquarium so be advised, these are for use in fish tanks that run with an elevated pH level.This group weighs 40 pounds and everything is clean and ready to use right out of the box.
