Granite In The Aquarium......yay Or Nay?

[micko]

I'd always believed granite was suitable for tanks but someone mentioned that granite leeches chemicals into the water colum.
Is this true?
I've lots of granite, clean, well washed (been part of a stone wall for over 100 years) its the grey and pink granite if that helps.

Thanks in advance.

i would have thought granite was fairly unreactive. therfore pretty safe to use in aquaria.
