Josh! Man, oh man!
I use diluted (sometimes full strength) muriatic but ONLY to clean pumps, parts, etc.
I have long shaken my head at the sale/keeping of z and p in this hobby. People keep these things and have no idea. You had good idea and still... These things are bad, bad, bad.
The lessons, because the do not keep clearly will gain no traction, are:
1. Any and all maneuvers with rock containing z/p, including fragging or anything, should always be done outside. Period.
2. If acid or vinegar washing/soaking rock, even if you do not think you have z/ps, must always be done outside (there are other hidden nasties and the dying organisms can be dangerous).
3. If acid or vinegar washing/soaking rock that you know has z/p, not only do so outside, but do so in a bin with a lid, put caution tape around it to ward off curious eyes.
4. Always, always wear eye protection and gloves, when dealing with anything containing z/p.
People will ignore. People will put these things in their tanks without reading about them first. Because Josh knew about them, perhaps subconsciously he was more careful, left the room, looked away rather than at, or, he just got lucky. Everyone ought to be aware that there is nothing new about anything in this post.
Be safe, people!
