Noob question on live rock curing.

[mccloud]

If I bought some Tongo live rock recently from a fish store.And I'm unsure now of what I bought.

1.Are they typically cured or uncured rock sold at stores(Petco)?
2.How damaging would it be if I added just 7lbs of uncured LR in a 90 gallon tank? Will anything bad happen?

First off, do you see any dead or decaying material, whitish areas, sponges? If so, cure!

Also if it smells rotten, probably it would be wise to cure.

I did get a couple pieces of what they called "figi aquacultured rock" at petco. It was already cured and in great shape. I was really suprised. They sent it home in bag with water and I dropped into my tank and it has done great. Gotten beautiful color to it. I supposed it is the same for you. This came out of a display tank that was fully submerged opposed to a circulating tank like some of the smaller LFS's use.
