I just picked up a used 120g tank. It came with about 2 inches of crushed shells and ~100lbs of dead white rock/coral. The system has been sitting dry for a couple of years.
- Do I need to "cook" the rocks before I seed them for live rock?
- Should I just chuck the crushed shells or can it be used? I intend to use a live sand bottom.
- Can anything be done in the tank as it is currently empty except for the shells.
- It also has a used aMiracle sump which is incomplete. Should I try to convert it to a live rock/sand sump or start with something else?
