Using "old" live rock

[Rani]

I have dried out live rock sitting in my garage, been there for a year now and wan to add to my new bigger tank with my existing live rock from my old smaller tank. How should I clean it? Tap / RO / salt water? Any advice gratefully appreciated!

I would use RO water. You know anything that was alive on that rock is dead now right? So it has to cure, either in the tank (sounds like that's what you want to do) or in a different container.

What I do is a bit overkill.
- give it a reasonable scrub
- throw in a drum with a power head and a 1-10 chlorine mix and leave for 5-7 days.
- take out leave in sun for a few days
- put back in drum with rodi water and lanthium chloride treat it. This part I feel is the most important. This gets ridof most built up phosphate in the rock.

- take out leave in sun for a few more days then start to aqua scape

Actually I've revised my plan...to cycle my new tank faster I'm going to put most of my live rock into my new rock and add the old live rock into my old tank to keep the corals at the same position until my new tank is ready to transfer everything over. Is that a good plan?

Sounds like a plan. I'm a big fan of not over-thinking things. Lol.

Just be careful with how much rock you take out. The new rock isn't cycled yet so your loosing a lot of natural filtration. You may see a rise in ammonia and nitrite which will not be good to keep your inhabitants happy let alone alive. It's never a good idea to remove a reasonable portion of live rock from a tank

Yea I would use the old rock to cycle the new tank. Adding that to the pre existing tank will be trouble
