I have a few pounds of dry rock from brs (pukani and multibranch) I'd like to add into my tank. With my current nitrate problem, I want to make sure they are perfectly clean of any and all die off and debris before I put them in there. I've been recommended a bleach and vinegar method. I don't like bleach, so I'll go with the vinegar. I was advised to soak them for about 10 days in vinegar. My question is, does it matter what kind of vinegar I get? Should I use the pure distilled white vinegar? Or can I use just the regular brown vinegar stuff?
