Nice rocks you got there. The texture looks really good. I hope it looks good underwater.

I may be wrong but I do know that if it sizzles it means that the the calcium levels are high in that rock, also it might raise Ph. It doesn't mean you can't use it but in planted Aquariums you want a more lower Ph. Good luck and hope they turn out GTU "positive." lol
