I would like to add some small stones from my yard into my tank. I was going to sterilize the stones first. I was going to avoid stones with high calcium carbonate levels. Any problems with this plan? Thanks. gwand
Hello gwand. You can use the old vinegar test on anything that you'd like to put into your tank. I typically put an eyedropper full of vinegar on the piece and wait to see if there's a reaction of any kind. If there's nothing after a couple of minutes, then the piece will be safe for the tank.I would like to add some small stones from my yard into my tank. I was going to sterilize the stones first.

Totally agree on this. Vinegar can have some quite minor reactions to other pH altering minerals such as dolomite, Ca/Mg carbonates.The vineger test works, but I like testing with Muriatic Acid
