MarcoRocks Coralline Premium Shelf Rock- 20lb, or 40lb box

This new Coralline-colored rock features all the classic benefits of MarcoRocks. This is the unequivocal perfect choice for creating flat reef ledges to bridge MarcoRocks’ Reef Saver or Hybrid Rock together. We highly recommend that your start with MR’s Foundation Rock in order to ensure a strong/ stable base for your aquascape.

These rocks are free of any pests since they’re kept dry, and most importantly, safe for all pet environments.
