I just picked up a 65 gallon tank from my friend who wanted to get rid of it. It was sitting in his basement with about 100lbs of liverock and a 3" aragonite sandbed. It had a lot of algae growing in it, but no fish or anything...so he decided to put bleach in it to kill the algae. Well, this was months ago, and for a while now it's been sitting empty till I bought it from him. Is there any way I can salvage the liverock (now dead of course), and use it as base rock? How bout the Aragonite?
If so, how do I go about getting it ready to use in the tank?
