I can't remember how much acid to water off he top of my head, but I did one rock at a time because some get eaten away quickly. I had the acid tub, then a tub of tap water with a wack of baking soda in it and then just an empty tub. I put a rock in the tub? Watched it fizz, checked every 60 secs or so. Most rocks were 3-5 mins each. As soon as each one was done it went in the baking soda bath until the next rock was done.
As said, the acid will damage concrete in the garage...even one drop will be forever etched.
After you're done, check the ph with a digital ph meter and just keep letting it cir cute with a powerhead in ro until the ph is back over 7. Then empty it and refill with saltwater and add your shrimp. I prefer to ghost feed some pellets, like maybe 10 a day. Shrimp are huge and take a long time to disintegrate.
