Arches & Tunnels

LifeRock is infused with spored bacteria to aid in biological performance, along with millions of micro and macro passage ways CaribSea’s Shapes Dry Live Rock is perfect for the environmentally friendly aquarist.

• Creates a mature looking reef instantly.
• 100% safe for all marine animals.
• Unique pieces.
• Environmentally friendly.

CaribSea LifeRock is made of an aragonitic base rock, instead of the typical cement used by many other artificial rock creators. Every rock contains a network of micro and macro pores that intertwine within the rocks internal structure, creating the perfect environment for natural nitrifying bacteria. LifeRock is manmade and does not affect our natural resources, making it the perfect option for all marine fish, invertebrates, and corals.

Every LifeRock from CaribSea has an artificial coating and texture that mimics natural coralline algae after being in the ocean for years. Depending on the animals that you have in your aquarium, they may pick at the coating on the rocks which will not harm them at all, and over time live coralline algae will cover any spots on the rocks that may have had the coating picked off.

Every box of Shapes LifeRock contains a mixture of arches, rings, and tunnels giving you unique looking pieces that can be used on their own or as accents to the rest of the aquascape.

How much rock do I need?

Knowing exactly how much Dry Live Rock you will need can be one of the hardest questions to answer since every tank and rock will be slightly different. A general guideline for dry Live Rock, we suggest 1 pound of rock per gallon of display tank volume and may vary depending on your overall goal for the aquascape. We always recommend purchasing a little extra dry rock to ensure that you will have enough to complete the aquascape you are looking for, any extra rock can always be broken up and placed in your refugium, overflows, and sump for added filtration.

What’s Included?

20lbs CaribSea LifeRock Shapes

Shipping: All rock can be fragile. Indiefur makes every effort to securely pack any type of rock. However, we have no control how courier handles it and it may break during shipping. Unfortunately, this is not covered by insurance so we are unable to replace broken pieces.

Setup & Use

Dry rock, so there are no pests, no nuisance algae and no die-off. It goes straight into a new tank with no quarantine period — that is the main reason to choose it over live rock.

Build the aquascape dry and outside the tank first. The arches, rings and tunnels are shaped to interlock, and finding the arrangement you want is far easier on a table than with your arms in the water. Bond the joints with a reef-safe cyanoacrylate gel or aquascaping epoxy for anything tall or overhanging.

Expect about four pieces in a 20 lb box, ranging from softball to football size, so plan the scape around large forms rather than small ones. At CaribSea’s guideline of roughly 1 lb per gallon of display volume, one box suits about a 20 gallon aquascape — buy a little extra, since offcuts are useful in the sump and refugium.

The spored bacteria in the rock wake on contact with water and seed the filter, but the tank still has to cycle. Test ammonia and nitrite before adding livestock. Fish may pick at the coralline-mimicking coating, which does them no harm; live coralline grows over the bare spots in time.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.
