reef tank

A reef tank is a specialized aquarium designed to recreate the natural environment of coral reefs. It contains live corals, marine fish, and invertebrates, all thriving in carefully maintained water conditions—such as specific temperature, salinity, and pH levels. The setup often includes advanced equipment like filtration systems, lighting that mimics sunlight, and sometimes live rock to provide habitat and biological filtration. Reef tanks require regular monitoring and maintenance to ensure a healthy ecosystem, making them a popular hobby for enthusiasts interested in marine life and sustainable aquatic ecosystems.
