Coral Rx is an anti-bacterial treatment designed to protect corals from bacterial infections and diseases. Ideal for treating freshly cut coral frags or any type of coral experiencing signs of stress, it ensures a safe environment without harming beneficial denitrifying bacteria in the aquarium ecosystem. To use Coral Rx effectively, it's essential to follow the preparation steps carefully: turn off your skimmer, discontinue carbon filtration for 72 hours, and remove phosphate removers during treatment; filter socks are recommended for better water clarity.
