This kit is designed to be a mix of rock perfect for Reef and Fish-only systems between 20-35 gallons in size. Included in the kit is the following-
At least 15 lbs of Premium Shelf Rock
At least 6 lbs of Foundation and risers.
Finished results will always vary! Place the Foundation Rock on the bottom then layer the Shelf rocks to create bridges, arches and caves.
You can also glue the scape together using any coral glue or E-Marco 400. The latter will give you a concrete like bond!
Rinsing in freshwater is not necessary but will minimize dust that might initially cloud the water.
