Marco Rock Dry Boulder


Product Information

100% PEST FREE!!! 


Marco Rocks was founded in 2006. Spawned out of the belief that our industry needed a responsible "green" alternative to wild collected live rock. We quickly out grew our Mass Location
In 2008 we expanded into a Key Largo location and thanks to your overwhelming support we quickly out grew that location also.


In 2010 we moved to our current location in Homestead Florida, A fully licensed Florida aquaculture facility on over 5 acres. Now exporting to 7 countries, we produce all of our own rock products and are the largest producer and shipper of aquarium rock in the USA. 


How much rock should I buy?

If MarcoRocks will be used as your primary biological filtration, the rule of thumb is 1 kilo per gallon. Depending on what type of scape you are looking to build.

If MarcoRocks will not be your primary Bio filter, We would recommend that you let whatever look is pleasing be your guide.


Can I add rock right into my established tank?

We do not recommend our rock or any other rock right into an established tank without testing first.

However you will find our Key Largo rock 100% free of organics or "pre cured" this makes it safe to tank in an established system without fear of an ammonia spike.


What is a cycle and how do I cycle my rock?

Cycle most often refers to one of two things with regard to live rock or base rock.

 a)The amount of time before your rock can act as a biological filter

 b)The amount of time before dried organic material and die off is rendered harmless


 When cycling a new system I recommend using a bottled bacteria product for some extra bio diversity you can also add a cup of live sand and a small amount of live rock from an established tank to your tank. Because there is no organic material to die off and create ammonia on our rock it is 100% safe a ready to use. All our rock is mined from old sea beds from millions of years ago when once all our seas were fresh and supremely clean.
