Aquarium Salt vs. Rock Salt: Differences, Benefits, and Uses

Aquariums are great places to bring tropical fish, but one thing you need to remember is that salt is necessary for them to live. Without it, they will die. Aquarium salt is a popular additive for fish tanks, as it helps control water hardness and provides a mineral balance. It is also used in marine aquariums to help keep the water clean and clear. On the other hand, rock salt is not typically used in fish tanks but is often used in salt marshes and estuaries to cleanse the water by absorbing moisture and toxins.
