Decommissioning a Tank

[JCJones]

Hi guys, any tips on how to clean out a marine tank?
Our 300L tank has died so we need to clean it out (to get rid of the smell) before I'm game enough to start again in a few months.

We had massive white spot/marine velvet issues which let to toxic ammonia levels in a few days, all gone. Also any idea if we can reuse any of the live rock or will it be too contaminated?
Thanks,
Joan

If you thoroughly clean the love rock then you should be able to reuse it, if you don't want to clean it, you could restart, let the LR cycle for 3-4 weeks, and test the levels.
