Caper Posted November 18, 2007 Report Share Posted November 18, 2007 Was at the beach the other day with my grandson and I picked up a few rocks to try in my tank. There's nothing particular about the ones I took as I couldn't really take my time to look since my main reason was to be there with Brayden (we had lots of fun ). I didn't have much vinegar so was only able to add a couple of drops to each one and nothing happened, if you think I should get more vinegar to put on them I will? They are presently boiling. Since the beach is on the ocean would salt be an issue? Caper Quote Link to comment Share on other sites More sharing options...
Caryl Posted November 18, 2007 Report Share Posted November 18, 2007 Salt won't be an issue because it will just wash off. They should be fine without more vinegar added. It is the white rocks you have to watch for as they can contain lime. Have you got a local rock and mineral club? They could tell you what the rock was and whether it is inert.

OscarBoy Posted November 18, 2007 Report Share Posted November 18, 2007 mind my dumbness bvut wat dose the vinegair do? Quote Link to comment Share on other sites More sharing options...
Caryl Posted November 18, 2007 Report Share Posted November 18, 2007 The vinegar test: Pour a little vinegar over your rock. If it fizzes, don't use it as it indicates the rock is not inert (ie won't alter the pH). Vinegar reacts that way to lime. Quote Link to comment Share on other sites More sharing options...
OscarBoy Posted November 18, 2007 Report Share Posted November 18, 2007 ohk. caryl do u know any were in welly that sell good lime stone rocks as i just have a massive boat a peice of drift wood and bubble walls in mine and i thort it would look better if i put it how other people do with the lime stone rocks Quote Link to comment Share on other sites More sharing options...

Anyone coming this way over the holidays? You could load up the car boot Quote Link to comment Share on other sites More sharing options...

Caper Posted November 18, 2007 Author Report Share Posted November 18, 2007 Tried to post a pic of rocks but too much trouble, getting disconnected :evil: :evil: One is all "whitish" others have white on them, I don't have many or big rocks, will post pic when can. Nope, not club that I'm aware. But didn't you say white has lime, and vinegar reacts with it, I did put vinegar on them all and nothing happened???

tHEcONCH Posted November 18, 2007 Report Share Posted November 18, 2007 Quartz, and a whole lot of other things, can look white so white doesn't necessarily mean lime - if they didn't react with the vinegar they should be fine. Alternatively, put them in a bucket of tank water (which you should have tested to get PH etc.) and measure for PH etc again after a week. If there is no change, you are fine Quote Link to comment Share on other sites More sharing options...
Caryl Posted November 18, 2007 Report Share Posted November 18, 2007 Conch is right with both his comments (re white that isn't lime and putting them in a bucket and test over a week). Quote Link to comment Share on other sites More sharing options...
Caper Posted November 19, 2007 Author Report Share Posted November 19, 2007 Before I add the rocks, should I leave the water sit in the bucket for any length of time before I test it? Caper Quote Link to comment Share on other sites More sharing options...
