Marco ReefSaver Foundation Rock
MR Foundation Rock- each piece is approximately 2.5 - 3.5lb.
(Formally known as Key Largo Single Sided Prime Cut rock)
Welcome to the dawn of stable, architecturally sound aquascaping.
Natural top and a smooth cut bottom making it the perfect choice for smart aquascaping.
We recommend placing this rock under any rockwork at the boundary layer between the glass and rock display. Separating them by 4-8" allows the rock work to "float" above this bottom layer, promoting healthy flow around the rockwork and over the substrate. Foundation rock can be siliconed to the glass if desired.
Rock sizing is not guaranteed but typically 6-10" in diameter.
