Is Flagstone safe?

[Severus]

I have ALOT of natural flagstone available that i could use to make some caves or just add to my aquarium. I was searching the internet and couldnt really find an answer when it came to flagstone. I am wondering if anyone has used flagstone before in their aquarium or if it is a definite no. I could always soak it in some water and see if it raises the ph, i just wanted to ask first and see if anyone had some answers. Thanks a lot!:22:

although i can find it that simple either i think if you go through the normal cleaning process it would be fine just as if you were to do anything else. a trick for something like this is to try a small piece and watch how affects everything.

Thanks for the help. I was thinking ill probably end up soaking a piece of it for a few days and checking how it affects the water.

that's great see you're already on it. that should be the easiest way to find out if there are any problems.

Yea, i figured unless someone actually has Flagstone in their tank the only way ill be sure is to soak it. Thanks jman

wow that is a great technique how did you learn that?
what does it mean?

Im pretty sure it means there are chemicals in the rock that will affect your aquarium. Thanks jeff
