I acquired a salt tank at my most recent relocation and it was a disaster. Worms everywhere and the water was absolutely filthy. I didn't bother testing after seeing nitrates shoot into deep red before even allowing time for solution to fully finish. Anyway, after killing the tank I put the rock in a tub outside my house. It's been out there for over two months covered in snow in 5-15degree weather. I had hoped this plus boiling the rock on my propane burner for a few hours would suffice in order to use this rock again. What do you think? I really don't want to do the long process of curing in tubs with air stones and massive water changes for months. Thoughts?
