Using my sandbed from old to new tank?

[Tom R]

When I used to have sand beds in my tanks I would always use some of the old sand bed to seed the new and the rinsed sand that I was using in the new set up.

I was under the impression that seeding the new set up with sand and live rock from a running system would always speed up or eliminate the time to cycle the new set up.

Good luck Laurie
