I just got in a package of live rock. I had my 30 gal trash can ready with salt water and all the requirements for curing the rock, then I read an article on associated.com. The link is [URL]http://www.associatedcontent.com/article/153683/how_to_cure_live_rock_with_little_die.html?cat=53[/URL] Instead of killing the rock and flushing out all the dead stuff over a period of weeks or even months, this article give the opposite approach, it feed the rock and try to preserve what life there is left when you received it. The title is "How to Cure Live Rock with Little Die Off" So, that's what I'm doing. I put the rock in a 10 gal tank, feed it Spectra Vital and put a actinic light on it 24/7. After an hour the ammonia reading was .5, I'll keep the forum informed on how this experiment works out. Geo.
