MarcoRocks Shelf Rock Natural Aquarium Rock – 20 kg

MarcoRocks Shelf Rock is natural aquarium rock in flat, shelf-like pieces, ideal for building ledges and overhangs where corals can be placed. MarcoRocks describes its rock as once-live natural reef rock made of all-natural calcium carbonate, with no chemicals or additives, and you can often spot fossilised ancient corals in it. It arrives free of pests and organics, ready for aquascaping.

Planning your aquascape

Shelf pieces work best as ledges and tables resting on sturdier base rock, giving flat spots for corals to sit on. Lay the rock out on a towel beside the tank and plan the layout before anything goes into the water; reef putty or epoxy can secure key joins. The 10 kg pack suits a smaller reef or extra ledges for an existing scape, while 20 kg allows a larger build. As this is dry rock, let the tank cycle before adding livestock.

Good to know

Rinse or soak the rock before use, build on the aquarium floor or a stable base so it cannot topple, and test water parameters as a new aquascape settles.
