I received some rock that came from a "crashed" tank. Not sure what made the tank crash. I believe it sat dry for well over a year in the sand and salt. Pretty sure once the tank crashed, they just let everything sit and "rot". The rock was bone dry when I got it. Washed off the sand and salt and let it sit in some Rubbermaid containers for a day, then changed that water and did that again for another 2 days. Noticed the rock starting to smell. Put the rock in the bathtub (in the spare bathroom that goes unused) and rinsed it off several times. Then let it sit in a tub of water for 2 days. Water ended up draining out of the tub one day when I went to work and I came home to the smell of death in the house!
Decided to toss some bleach in the water to get rid of the smell, that has worked but now I need to get this rock to the point it can be put into a tank at some point soon. Not an established tank! I've read the thread on RC (club thread) on muriatic acid wash.
First off, where can I get this stuff? I called Namco pools and they don't sell it. Before I get the wrong stuff I figured I'd ask here first.
Second, I want to make sure I don't make a toxic cloud and wipe out the neighborhood too. (Need help here) So, I should rinse the bleach off with a ton of dechlorinated water. I have some Prime or generic Petco dechlorinator I can use. Once that is free of the bleach smell then I can use this acid? How diluted should I use this stuff? 10:1? I assume this stuff must be done outside(...live in a condo with limited outside space)? Can I use a regular rubbermade/Sterlite tub? There is a good bit of rock here, probably 3 of the 20/30g tubs full. From there let the rock sit in this acid wash for an hour or two with a powerhead? Then add a ton of baking soda to neutralize the acid? Rinse the rock good and let it dry. I'm sure I'll do the rinse and dry step a few times for piece of mind. Then I should be good to start this rock in saltwater?
Am I on the right path or is this a suicide/homicide by acid mission?
