nothing against low posters or people with less time on their join date. shoot anyone can post up 600 posts in the aquarium lounge. oh and i don't think i called myself an experienced reefer. there are some people that you learn from here. i'm just giving a tip on looking around for them.
all i'm saying is that if you take an hour or so and research many of the mod's replies to "bleach" i would place my trust in them. i would place several specific links, but i don't want to single out any single person and it's pretty simple to click "search" and type "bleach".
i did not tell him to throw it in his tank this afternoon. he has it, it's basically free to keep it sunk and test it for a long time, even though it shouldn't take a long time. i don't even have any pool bleached rock, but it only took me a minute of wondering to find out that i would try to save it for a month or so. imagine what i could find out if i actually searched out the chemical base and difference between regular bleach?
i've heard also of people boiling chlorine off and heating it up on the driveway to speed up the process.
like i said before if you come across some you don't want in all your wisdom, i'll cook it up. i have all the time in the world.
