Live rock

[Zane08]

I got a tank used with some live rock and its all cycled and stuff can i add a piece of dry rock or two just like that or would it hurt something in the tank newbie question but kinda new i bought my tank from a guy just kept the water live rock it had and sand so i dont know much about cycling the rock

Not sure I understand. Are you saying you purchased the tank with some live rock and you just want to know if you need to do anything with the rock or just set up your new tank with the rock the way it is?

He had the tank over two years i bought it kept the same water and sand and live rock just transported it all in jugs but i want too add more rock i seen the dry rock was cheaper can i buy some and just throw it in my tank all ready its a 210 gallon if i throw dry rock in there would it mess with my tank stuff or no

Dry rock - not it shouldn't mess anything up. I've done it multiple times. I usually get it and rinse it off thoroughly and let it dry in the sun for a day.

If the rock is clean and free of organics, you should not have a problem. If the rock has dead material on it, it could cause an ammonia spike. If you only have rock and sand, you can add it and let it cycle. You don't mention if you have fish or anything else a spike could injure.

That's why I usually give it a good wash and let it soak in the sun. The sun will help

I've also done a bleach bath just to be safe. A day in the sun will eliminate any traces of bleach.

We've added dry rock here and there after a good soak and wash to get any stuck stuff out. We just keep an eye on parameters and if anything changes, are prepared to do water change.
