Soooo I have a large container or what was once live rock from an old aquarium. it's easily 125-150 lbs. I want to reuse in my newish tank. nothing odd there, happens all the time. to be safe i soaked some of the rocks and tested them. ammonia reading .75 ppm after 24 hours. i go back to the rock i haven't soaked yet and notice a smell. i have hunch my cat may have used this as an alternate litter box on occasion!!! grrrrr!!!! so question. can i rise the heck out of the rock and then pretty much cure as normal and one all reading it zero assume it's aquarium safe again? wife has me on a strict budget and i hate to spend money replacing all this rock if i dont absolutely need to.
