Thank you to all those who chimed in and offered advise.
It helped me a lot while going through the process. Its a little over whelming at first when dealing with such substances but not that bad after all.
Just thought I should update you all of my progress with curing process.
I ran out of acid for the last batch so have to redo some of those rocks as the little bit of acid didn't really do much.
Meanwhile, the rock that was completely cleaned to my satisfaction is now in the heated salty water about the enter the cycling process.
I'll be adding in Brightwell Aquatics Microbactor7 and some food pallets to jump start the cycling process. Hoping the cycle will complete in two weeks.
