Lava rock in reef tank

[I_Got_Crabs]

I bought a bunch of used rock, bleached and dried it, then created and aquascape with stonefix cement and acrylic rods. I realized after putting it all together and cycling it for 5 weeks that there's a small piece of man made lava rock in there.

My questions are:

1) Will the rock continue to leach contaminates into my system if it was previously in a saltwater tank for almost 2 years?

2) Are all the other rocks in the curing bin now contaminated? If so, what do I do?
