It's a magic trick :P
It's going to be a slow process. I'm doing a bunch of reading/research regarding the muriatic acid baths we talked about.
I have approx 100lbs of rock that have been sitting "dry" for 5+ years. Prior to letting them "dry" I had cooked them.
Ie: Let them sit in a DARK TUB with him High flow and RO Salt Water with several water changes weekly.
RC's thread mention bleaching them ACID, there seems to be various opinion on the order of execution.
Is bleaching necesarry? or should I only do the ACID bath.
You can acid bath it or you can just bleach it. I mean acid bath will take away almost everything left over on the rocks that is in a organic form, acid should be around PH1 and I think bleach is sitting around PH2 so same idea just not as strong.
Do you think my local hardware store will have this muriatic acid? (home depot).
Home depot or Canadian tire. I know it must be freezing cold out there so dress warm. 
There's also a mention of using Baking Soda or Draino to neutralize the ACID.
After the rocks has been in the acid for a few hours or till you are satisfied with them then you put the baking soda in to neutralize it.
It's cold in Ottawa (as i mentioned yesterday)
I'm hoping to find a warmer day to do this outside without the water freezing.
Any input would be appreciated.
