Easy to aquascape with

All-natural calcium carbonate rock

Eco-Friendly, sustainable rock

Pest free

Made of all-natural calcium carbonate, MarcoRocks Hybrid Rock is an exceptional way to start your saltwater aquarium aquascape. Combining the best of standard Reef Saver and Shelf, MarcoRocks Hybrid Rock offers the height and robustness of Reef Saver rock, while also featuring ridges and overhangs found in their Shelf rock. Because these are pre-boxed by MarcoRocks, we are unable to take special requests for rock sizes or shapes. This is a natural product, so the size and number of rocks in each box will vary. 

Eco-Friendly & Sustainable

MarcoRock is not harvested from a marine environment and has no negative impact on our delicate reef or marine ecosystems. Combine with their no-chemical cleaning process, you are left with great looking and pest free rock that's also environmentally friendly.

How much rock do I need?

Every tank will be slightly different, so as a general guideline for Reef Saver Hybrid Dry Live Rock, we suggest 3/4 to 1 pound of rock per gallon of display tank volume. This amount may also vary depending on the exact look you're going for with your aquascape. We always recommend purchasing a little extra so that you have a variety of pieces to choose from and can build the aquascape you're looking for. Extra rock can always be broken up and placed in your sump for additional biological filtration.
