Rock from lake

I was by my lake the other day to see if I can cure my rock in there and I saw this nice sized rock by the banks. I was wondering if I can take it and cure it in saltwater for like a month in a dark place to kill off the FW bacteria, then use it in my tank. Would it work? Any harms?

Thanks!

As far as using an random rocks out there you might get away with it you might ruin your tank and totally have to reset it up again. I've seen people go as odd ball as use broken up lumps of concrete in a tank and it works. I have also seen people you use unapprove rock have MASSIVE algae or cyano problems from stuff leaching out of the rock.

I would keep making rock like your doing or order some dry base rock.

 

Thanks! I was just curious cause the rock looks really porous and got alittle carry away.

I lives within 5 miles of his city!!! I am going to ask him where he got it from and go rock hunting this weekend!

Thanks Covey!

 

Is it really worth chancing a non marine rock of unknown makeup, that might leach copper and other harmful metals into your tank?

 

i was silly thinking about putting a rock from a lake in my tank.

but i am going gonna see if i can find out where i can get the rocks from a reef as the link Covey mentioned.

that'd be coo so i don't have to make anymore rock.

 

PM me when you find out where GKW seeing as we live right by each other.
