Would it be a bad idea to use rock that is used for outside home construction, as decoration for a freshwater setup?

Boil them and scrub the heck out of them to get them clean. Then put a few drops of vinegar on them to see if you get fizz. If you do, then do not use the rocks in your tank as they will alter your pH. If you do not get fizz, then they should be ok for use in your tank. Just be careful not to put in rocks with sharp edges and the like so the fish do not injure themselves.

Will do. Now I will have to get a big enough post to boil these in. I have been knocking the sharper edges off to alleviate the possibly of the fish getting injured.


Thanx
