Starting Over what can be reused?

[elpezgrande]

I have a 3 1/2 year old set up and I am going to be moving so I planned to break the tank down, recycle it, and start everything from scratch. I planned to get some new sand to have a fresh dsb. Is that necessary? I was planning to reuse my LR but was wondering if that needs to be replaced over time as well. So new LR too or can I reuse the old?

can use both. just make sure they are kept wet.
adding new sand and rock will only add to your biodivercity, but may also have hitchikers you don't want.

as far as a DSB in a display tank, this can get tricky...cause in time all DSB will basically crash. i would honestly go with 2-3 inch bed. i would even use the same old sand too. rock never goes bad unless out of water then it becomes dead rock....hope this helps
