Add additional rock in system

Hello everyone, I want to put in tank some more rocks and sow on side of the street big pieces of porous rocks. If I take some pieces of them and then bleaching then burning in stove, then can I cure them and use like liverocks?
And if I can cure them what kind of bacteria or additive I need to put in it? May be changed water from tank?

 

Absolutely not! Being porous only means they are probably loaded with contaminants that bleaching/baking won't remove, not to mention the fact that you don't even know what type of rock you're looking at. Some will leach heavy metals, silicates, or other minerals/compounds into the water.

Adding more rock to an existing tank is fine, but I would only recommend using dry base or cured live rock from an online distributor or LFS.

 

+1. You have to be kind of picky about what you put into your tank. If not you might end up with a real mess on your hands lol.

 

+2. Too risky.

 

Oh yeah not a good idea, anything could leach out that type of rock.

 

+3 Only get the rock from a trusted source.

 

so if I get from LFS dry rock base can I put directly to the tank or need to be cure also?
If cure what is the fastest way to do it?

 

you can just add dry base rock! from your LFS or an online reputable dealer, not a street, alley, highway, dirt road, stream, knook, cranny, crick, river, etc

 

I've never had any problems with adding it directly to the main DT. Just rinse off the dust and you should be good to go.
