What Is the Best Salinity for a Healthy Reef Tank?

A reef tank is a marine aquarium that typically houses corals and other invertebrates. The main goal of a reef tank is to maintain a delicate balance between the water chemistry, lighting, and filtration to create an environment that is conducive to the growth and health of corals. One of the most important factors in a reef tank is salinity, which is a measure of the dissolved salt content in the water. The ideal salinity for a reef tank is between 1.023 and 1.025.
