The 5 Best Reef Salts for LPS & SPS Tanks (2022)

When you own and nurture a reef tank, you already know that these elements of a tank require saltwater to survive. However, the process of getting saltwater is a bit more complicated than simply adding salt to a tank of water.

Aquarium ecosystems are very sensitive and can react to certain pH levels, chemicals, and levels of substances like calcium and magnesium very abruptly and without warning, which is why it’s so important to make sure you’re getting it right when making sure your underwater environment is as it should be.

This is where reef salt comes in. Professional reef salt is designed to create a saltwater ecosystem for your aquarium life to thrive in, all while making sure everything is balanced and that your plant life will actually survive. The Red Sea Coral Pro Salt is our favorite reef salt mix for both LPS and SPS corals, but comes with a heftier price tag. Below we list our favorites.
