Using sulfuric acid??

I had another question of a different topic to ask. I bought a few rocks from a water garden nursery and they are labeled as river rocks. I read up on the need to use muriatic acid (sp?) but they only sold it by the gallon. I wanted to try something smaller and I found sulfuric acid at a pool supply store. My feeling is that both sulfuric and muriatic acid both have strong acid properites. Has anyone tried using this before? I went ahead and put a few drops on each of the rocks and nothing happened so I'm assuming the rocks are safe for aquarium use but I want to make sure by asking the experts here

I'm assuming that you were doing the fizz test for carbonates? If that's true, then sulfuric acid does the job just fine.
yeah thats what I was doing...i'm glad to hear that.
