found a few rocks that caught my eye.
ran the vinegar test and it all checked out.
anything else i should look into or is the acid test pretty conclusive?
if that's all good, i'm assuming they're safe to use once they're cleaned up?
acid of rocks
Re: acid of rocks
I'm always pretty cautious when it comes to adding new rocks to my tank. I've got a bunch from my neighborhood in there already, and I've learned to test them thoroughly before adding them in. I like to fill a bucket with water, check the parameters, then leave the rocks in for a day to make sure they don't affect the water quality.
