MarcoRock’s Hybrid Rocks are versatile and combine the best features of both shelf and reef saver rocks. They allow you to create ridges and overhangs while providing the mass, height, and shape needed for dynamic aquascaping. We recommend using Hybrid Rock above MR Foundation Rock. To connect Hybrid Rock structures for more dramatic caves and ledges consider adding a few pieces of MR Shelf rock to the mix.
Can be bonded with E Marco-400 for permanent placement.
