If you're looking for natural Tonga branch rock with fantastic shapes and color, take a look at this rock. Just like the counterparts in the natural coral reef, Tropic Eden Supreme Tonga Branch Morroca Reef Rocks come in purely irregular and random shape and sizes. Every piece is uniquely made and hand-crafted so there are no two identical pieces found anywhere in the world! TE’s STB Morroca reef rocks have all been pre-cured in clean 33ppt seawater then further cured dry, and are ready for use in reef or other kinds of saltwater aquarium. What is so great about Tropic Eden Supreme Tonga Branch Morroca Reef Rock? Tropic Eden Supreme Tonga Branch Morroca Reef Rocks are composed of aragonite calcium carbonates, calcareous alkalis, reef-safe resin and selected reef minerals, which are mineralized and hardened by special heat process. TE’s STB Morroca reef rocks are stronger than natural Tonga branch rocks. The aragonite and calcareous materials from TE’s STB Morroca reef rock help stabilize alkalinity and the pH of aquarium water which are critical to the health of coral and other reef inhabitants. Unlike rocks made with dense and heavy solid cement concrete, TE’s STB Morroca reef rocks are full of tiny pores and are lightweight as natural Tonga branches. Beautiful Surface that Resembles Natural Tonga Branches Similar to natural coralline algae that grow on top of natural reef rocks, the surface of TE’s STB Morroca reef rocks is covered with a special blend of organic reef-safe pigments, reef trace elements/minerals, and natural colloidal compound that tightly fuse with the underlying calcareous material. The process creates a beautiful coloration of pink and purple coralline colors that will stay true and vibrant for many years even when exposed to lighting in reef aquarium. The true brilliance of the colors of TE’s STB Morroca reef rock can best show in aquarium water under full spectrum lighting. In normal healthy reef aquarium, TE’s STB Morroca reef rocks will get covered quickly by coralline algae like natural live rocks. In addition, the complex and rough surfaces of TE’s STB Morroca reef rocks provide trillions of microscopic holes, pits and surface area which serve as excellent home and shelter for the colonization of beneficial bacteria and microorganisms. Our research show that reef bacteria and bacterial biofilm have an exceptional propensity to grow on TE’s STB Morroca reef rocks. Random Shapes like Natural Tonga Branches TE’s STB Morroca reef rocks stunningly resemble Tonga branches found in the natural reef with great looking shapes that are so irregular and impressive!
