@Randy Holmes-Farley I am in the process of cleaning my rocks and kind of starting over. I’m using muratic acid and letting them soak for 15 mins in a 10:1 ratio. The first batch I used baking soda (sodium bicarbonate)to neutralize the muratic acid bath. Yesterday I bought sodium carbonate thinking it was the same thing but after reading more into it I have realized it is not. Will the sodium carbonate be ok to use to neutralize the muratic acid or is it not safe to use?
