Primo Reefs Has A Sustainable Alternative to Live Reef Rock

Ever since the hobby of reef keeping was started, the foundation of any new tank setup consisted of many pounds of “live rock“.  This live rock typically consisted of dead coral skeletons that made up the foundation layer of a reef or ocean bottom somewhere around the world.  This rock is removed, kept wet, and shipped to local fish stores around the world.  Like most everything else in the ocean, this live rock was subject to over harvesting and its collection has been banned from many places in the world such as Florida and Hawaii.  In recent years we have seen some viable alternatives to live rock enter the market which offer a sustainable alternative to ripping rock off the worlds’ reefs.  Primo Reefs is one of the latest options offering a new twist on live rock where they bring to market rocks that are mined miles inland and are never pulled from the ocean.


What is Primo Reefs Reef Rock?

Primo Reefs rock is 100% natural meaning its not man made or painted and thus won’t  fade or release out unknown substances over time.  The locations that the rock is mined from are chosen with the aquarist in mind meaning that the sizes and shapes are very varied.  Their rock is professionally cleaned after it is harvested in an extensive 6 stage cleaning process that ensures their rock is pristine before it goes in your reef tank.  This cleaning process also ensures that there is no curing required before placing the rock in your reef aquarium, unlike live rock that is pulled from ocean.  It is also free of phosphates and will not undergo any leaching over time.

Why Is Sustainably Harvested Reef Rock Better For Reef Tanks?

Like most in the reefkeeping industry, we are trying to do what we can to promote and use products that don’t directly or indirectly have an adverse effect on the natural environment.  As we were upgrading our main reef tank at ReefNation we knew we would need close to 500 pounds of rock to build the structure we wanted which is where we first learned about Primo Reefs.  Like most who have kept a reef tank before, we all know that once you get things in the tank and established, it is very difficult to get them out without taking the entire tank down.  With this in mind, we wanted to put the 500 pounds of rock structure in and not have to worry about hitchhiking pests like aiptasia anemones, mantis shrimp, crabs, and nuisance algae that usually accompany live rock that comes directly from the ocean.  When we were setting up our previous tank, we had struggled with ALL of these pests on aqua cultured live rock that we got shipped from Florida and it took close to 2 years to get all of the pests out of that tank.  In addition to no pests, we found the Primo Reefs rock to be extremely porous and easy to stack.  In fact we were able to add some of staghorn acropora corals simply by sticking the branches directly into the rock work.


Week 1 of new 300 gallon reef tank

We are on week two of having the new 300 gallon tank setup and already the little purple dots have started to show on the top indicating that coraline algae is starting to take hold.  It will probably take a few months for all of it to be covered in coraline, sponges and worms, but it does feel good to be making this rock work in our captive marine environments without any adverse affects on the ocean.  Overall we couldn’t be happier with our use of Primo Reefs reef rock and would recommend it to anyone looking for a more sustainable alternative to ocean harvested reef rock.
