I went to the mountains and picked up a few cool rocks for the fishies, but im not sure if they are safe for them, I have done the vinegar test and there was no bubbles but there was a fizzing noise, does that mean there not safe? I've also heard that the vinegar test just proves whether or not it will change the ph levels, but wont assure the rock is safe. Is there any way I can know for sure? I want to build a cave with them but I don't want to risk it. Please help.
