Aquarium Advice Regular
So, I have some nice rocks that I picked up and I soaked them in vinegar and there was no fizzing. I cleaned them and sat them in a bucket of water to soak and added a hefty amount of vinegar. The next day, I come back and the rocks aren't soft, but they have granules that shed off of them lightly leaving a whiter underneath layer. I recleaned them and put them back into the bucket without vinegar. Could this be an issue? If so, what would happen?
