I think Burnsss is saying that he has crushed coral in his tank and he wants to know if he should move it to the new location, move part of it to the new location or replace it all when he gets to the new location....I think?
I am not too familiar with crushed coral or it's harboring of nitrates, so I cannot comment on this.
Since I have never moved tanks, I can only speak of what other's have stated.
Most people will probably tell you to go ahead and replace ALL the substrate (sand or crushed coral) when you get to the new location.
Another method people have mentioned is to keep VERY LITTLE WATER, only enough to cover the substrate, and move the whole thing to the new location, trying not to disturb the sand or crushed coral bed.
In any event, good luck with your move!
