Where did you find it bro?

from a company that do landscaping.

If I remember correctly, you can actually use vinegar to test the ph. If it fizzles when contacted with vinegar, it has low ph properties...

try that, no fizzle = safe to use?

If fizzle, wouldn;t it raise the pH when you put in your tank?

If fizzles, its acidic and would lower yout ph.

If it fizzles, it means that the rock contains compounds that will make water harder, thus increasing the pH.

That's what I thought too

Oh!

Sorry, got it the other way around.

You can measure the PH value of a pail of water, then put the rock and maybe after 1 day measure the PH again to see if it goes up or down.
