evan9381 Posted September 8, 2007 Report Share Posted September 8, 2007 need some limestone. not huge pieces, and i dont need a lot. maybe 20-30lbs? using it for a fish tank to keep the pH up. if you have some from taking down some landscaping projects, or just happen to have some sitting around you dont want, let me know. can be in bigger pieces, as long as they can be broken into smaller pieces not looking to spend much...cheap to free is my price range let me know what you got.

evan9381 Posted September 9, 2007 Author Report Share Posted September 9, 2007 send me some pics. i read one way to tell is to drop vinegar on them, and they should fiz up. a couple people said though that vinegar isnt strong enough and diluted hydrochloric acid is the best way to tell...im in a search now to find some to test a few rocks Link to comment Share on other sites More sharing options...
