i would be cautious using anything man-made. better go with natural stone. even natural stone you need to be careful since it can alter your ph like hawk said.
here's a good test:
Here's a better idea: if you have a nitrate test kit, you may also already have a better test than vinegar for lime content in rocks. My Aquarium Pharmaceuticals Nitrate Test contains two bottles of prepared solutions. Solution #1, labeled "Caution: contains hydrochloric acid," comes in a handy squeeze dropper bottle. If a drop or two on a candidate rock fizzes, or even bubbles, that rock would raise the pH in the aquarium
yeah i just learned that recently too after buying some rock for my planted tank. some folks on another forum told me about this quick and easy test. just take your bottle with you when you go rock hunting!wjones1970;1988728;1988728 said:Thanks I did not know that you could test a rock like that. I also have the test kit already so I just need to find some rocks now.
