NATURAL Lace Rock - Aquarium / Terrarium / Bonsai Stone

Lace Rock is a very well-known volcanic rock that is widely used in freshwater and saltwater aquariums as well as terrariums and bonsai tree arrangements.  This highly porous rock is excellent for cultivating beneficial bacteria in aquariums.  Lace Rock can dramatically raise the pH of aquariums, which is of no concern in saltwater aquariums.  In freshwater aquariums, it should only be used with animals (such as African cichlids) that thrive in or are not particularly sensitive to unusually high pH. We package all of our exotic stones with ample padding/protection during shipment.  However, we recommend rinsing any residual dust with non-chlorinated water before aquarium usage.   *IMPORTANT* Please "Choose a Variant" above before adding this item to your cart.
