CaribSea’s Rubble Zone is a premium-quality aragonitic material that is ideal for use in a variety of freshwater and marine applications. Limited only by your imagination, this ultra-versatile product will help you anchor coral frags, craft breathtaking visual displays, create filtration-enhancing cryptic zones, and much more! Each container of Rubble Zone contains a random selection (approximately 6 pounds) of 1″ to 4″ easily managable fragments.

A Few Rubble Zone Applications:

Creating Displays – Place Rubble Zone pieces as desired on the bottom of your aquarium. Surround a large live rock centerpiece with a cluster of Rubble Zone fragments to create a stunning aquatic display.

Refugium Use – Place Rubble Zone fragments along the bottom of your refugium. Makes an excellent substrate for macro algae holdfasts, and a superb growing area for copepods and other benthic food sources.

Cryptic Zones – In a crowded refugium, Rubble Zone can be used right in its container! Simply remove the label and drill several 1/4″ to 1/2″ holes. Refill the container with Rubble Zone and situate in an area of your sump with good water flow.

Entertaining Burrowing Fish & Inverts – Place Rubble Zone fragments in an empty aquarium, then add fine grain sand to fill the voids for a total depth of 3″ to 4″. Cover the entire aquarium bottom or create a dedicated section.

African Cichlid Aquariums – Place Rubble Zone as desired on the bottom of your aquarium. It provides stress-reducing cover for smaller fish, and helps prevent larger fish from disturbing finer substrates. Can also be used inside your filter to provide biological and pH support.

Pond Use – Rubble Zone provides exceptional biological and pH support in pond filters. Also provides similar support in aquarium filters.
