Do you think it's cured?

[trainfever]

I bought some new live rock tonight and placed it in my curing tank. I have a nano cube set up to cure live rock as I get it. My LFS has about 8 tanks set up to cure live rock. The tanks are marked with the date that the rock came in so you know how long it has been curing. Anyway the rock I picked up today has been curing since 5/11. I just went and looked at the rock and noticed 4 little feather duster worms open on the one piece of rock. Since these worms are alive and open, do you think the rock is cured?

Possibly...but I'd leave it for a few days and test for ammonia/nitrite/nitrate...if there is any ammonia/nitrite I'd wait until it is gone before adding it to an established system.
