Marco Rocks Coralline Foundation Rock 20lbs - box

Classic MarcoRocks Foundation Rock, But With a Coralline Appearance!

MarcoRocks Foundation Reef Saver Rock is the perfect base to any desirable aquascape. Each piece of foundation rock is cut flat on one side for stable placement and an architecturally sound aquascape. The natural rock top-side lets you place traditional rocks on top of the foundation pieces without creating excess pressure points or strain on the base of the tank. If you are going to with a bare bottom tank the look the foundation rock gives is awesome and even if you are going to be using a sand bed, placing a few pieces of Foundation Rock approximately 6" - 8" apart will allow for proper flow throughout the base of the structure and allow detritus to be swept away. 

MarcoRocks Reef Saver Foundation Live Rock, the environmentally friendly rock, works great for aquascaping. This rock is 100% free of nuisance algae and pests which can cause complete tank shut downs and is guaranteed to be free of aiptasia, bubble algae, parasitic isopods, mantis shrimp, acro eating flat worms, little red bugs, fire worms, predatory nudibranchs, pyramidellid snails and other common pests.

How Much Rock Do I Need?

Foundation rock will be slightly different rule than the traditional 1 pound per gallon logic, and we suggest one piece per foot of display tank, but depending on your display tanks dimensions you may want an extra rock or two to ensure you have enough to complete your aquarium aquascape. Ultimately, the best results will be given if you can support each rock structure entirely with the foundation rock while providing space for flow between the rocks. We have found that selecting a few different sizes allows for multiple options when it comes to having more creative freedom when aquascaping.
