Fancy Reef Rock Arches - 4 Pack - Real Reef

Real Reef Arches offer the beauty and function of Real Reef Rock in a natural arch shape. Each piece is handmade, averaging 8-14" in length, with unique variations in design. Sold in boxes of four arches, each with similar but distinct shapes.

Made from eco-friendly, natural materials, Real Reef Rock is lightweight, porous, and biologically active, mimicking coralline-encrusted coral skeleton rock. Its purple, pink, and red hues provide a natural reef aesthetic, while its high-stability pH makes it ideal for marine reef and fish-only aquariums. Not recommended for freshwater tanks.

Rock is naturally fragile, and some breakage may occur during shipping. We inspect and securely pack each box, but carrier handling is beyond our control. Shipping insurance does not cover breakage, so we cannot offer replacements.
