I rinsed the rocks then did the acid.
I'm not sure how long I was supposed to leave the rocks in there. I probably added the baking soda too early. A lot of crap came off the rocks, but there is still a good amount of dark brown and a few red spots still

I left them in the acid for about 2-3 hrs, until the bubbles had all stopped and popped. Then added the baking soda and let that sit for another hour just to make sure.
 Once it was all done there were still a few brown areas on the pukani.

When I did it, I poured acid in, waited until the reaction was over, then poured more in until the reaction stopped. Then I let it sit for a couple hours. Then did baking soda.

I only left my rock in for 5 minutes or so. I don't know what the magic number is, but I know I can always put it in again if I needed to.
It was bubbling like crazy and I wasn't sure what was all going on under there so I dumped the baking soda in between the 5 - 10 minute mark. As far as losing mass, I didn't notice any. I am sure you lose some, but I don't think it's significant. Today was the only above freezing day I think we may have for a while. I was in a bit of a rush. I think I might just toss it in a bin and let it cycle in the dark for a while in the basement.

To be honest I didn't even think about the loss of mass. If I had to answer I'd have to say not much.
