I had these rocks given to me but I do not know if they were in a saltwater or freshwater aquarium before. Can I put a rock from a saltwater aquarium into a freshwater aquarium? Also, what kind of rock is this? Is it safe?
No, live rock/sand dies if you put it in fresh water. It does not harbor BB. If you want to use live rock in a Freshwater tank, you still need to cycle your tank.Ms rose said:
Making the hardness rise means the pH is rising so if I just put some API pH lower then wouldn’t it be fine?Ms rose said:I would boil it to be safe, but from the sounds of it, it's ok to put in fw as long as your ok with a hardness rise. I'm just learning this so I'm not 100 percent sure if boiling will prevent this from happening, hmm, I can't imagine boiling would stop it from tpraising the hardness of the water but boiling will kill anything harmful for the tank.
