If it makes you feel any better, in my current 105 I used rock I got for practically nothing from a friend. He had the rock sitting in his back yard for over a year. Through the winter and summer it went and it looked quite bleached when I got it, But what he failed to inform me of was that the reason the rock wasn't being used and found it's place in the back yard was that it was completely covered with bubble algae.
Apparently the spores of such algae can survive some extreme weather. As soon as I submerged the rock in water.....BOOM!
