Coral Rock
Can I put coral rocks (were used in a Saltwater Fish tank) in my freshwater Fish Tank?

Some gave me coral rocks they had in their saltwater fish tank. Can I use those in my Freshwater Fish tank?

No you should not. I have a 50 Gallon Fish tank and I asked The owner of a fish store about this same type question. He said no because the coral changes the pH in the water which could kill your fish. You shouldn’t put anything from Salt Water tank into a fresh water tank.
