Tank Rebuild

[likwid]

Hey guys,

I plenty newbies mistakes with my first SW tank, and am thinking of taking it all apart and rebuilding it again. I would like to keep the current live rock, but give it a good scrubbing, replace all of the live sand with something more coarse (possibly crushed coral), use RO water, and keeping all of the current inverts I have in there right now. What is the best way to go about doing this? Will I have to cycle the tank again?

Thanks
