Rocks - how to prefare them?

[Cheese Specialist]

Hello,

I am wanting to re-decorate my 19US tank and I want to use one or 2 rocks. I found some in my garden. How do I prepare these and how do I know which are ok? I remember reading something about vinegar.

I did a search to find some info on here but it came up with too much for me to go through, but I will try whist I wait for your ever helpful responses.

Hmmm I wonder if FM would mind a pm...

P.S. The fish in the tank are in my sig. My ph is usually about 7.5, should I be worried about changes made by the rocks to the water?

The vinegar test is to see if the rocks will cause a change in ph of your water. If the vinegar fizzes, the rocks should be avoided. If it doesn't they should be ok.

For preperation, just boil them for a few minutes. Nothing can survive boiling water. Remember to let them cool before adding them to your tank or the temperature of the tank will quickly rise.

What ever you do DO NOT put sedimentary rocks in you tank such aas limestone, sandstone, or marble
