Live Rock/Live Sand

[jbjints]

My tank has been disconnected for almost a year due to construction that I've had done to my house, time and space is now available for me to reconnect my tank once again.

I was wondering how I should handle the live sand and live rock I once had. The water that I will be adding will be DI water (TWP), I had to totally empty my tank of water, will the live rock or live sand I once had become live once again or will I have to start from scratch by buying live rock and live sand?

Thanks in advance,

Joe

It would become "live" again however it will take some Lr/LS to seed it and would take a pretty long time considering the size of tank you are using. What I would do is use a couple pieces of the old rock to form a solid base to set new, live rock on top of. As for the sand, if you are going with e DSB and the sand you have is fine grade, it should be ok to use and seed with some fiji live sand from a vendor.
