The Coral Ranch

The Coral Ranch is a Florida-based aquarium brand making practical reef-care products for marine fish and reef-keeping enthusiasts. Founded by reef keepers, the company focuses on products its team uses in its own systems, with an emphasis on straightforward ingredients and dependable formulations. Its offerings include premium aquarium-grade nori seaweed, described as thick and 100% pure, with no added salt, oil, or flavorings.

The nori is intended for tangs, angelfish, rabbitfish, blennies, and other marine grazers, and is available in multiple sizes. The Coral Ranch also produces Guillard’s F/2 phytoplankton fertilizer, using the established F/2 recipe to help customers grow live phytoplankton. The concentrate is mixed in-house in the United States and supplied ready to use in a complete bottle.

Alongside its products, the brand provides reef-care guides covering marine phytoplankton and copepods, including their roles in reef-tank food webs and aquarium health. Products are sold through the company’s Amazon store, where customers can access Amazon checkout, shipping, and returns
