Transfer sand bed?

[Metrontech]

Hey looking for some help and clarification

I have a 55 gallon mixed reef which will be transferred to my new 120 gallon with 55 gallon sump

The current tank is 10 months old, so the sand is 10 months old

I vacuum the sand, or at least 50% of the sand in a reg basis

Can I just transfer it to the new tank?

I have read a lot about Re-cycling etc and nitrate boosts etc.

I am running high grade gfo in a reactor with zero phosphates and less than 5 nitrates all the time.

Any help?

I wouldn't. Or at least, not without washing it in tank water thoroughly. I did that once, my tank died

I'd keep the sand but put it all in a pail and stick in the garden hose & start stirring... When the overflowing water is clear, go ahead and dump it back in to your tank.

Not terrible advice at all, but using the old tank water will preserve a lot of the bacteria while getting rid of the muck. Whichever is easier really

It's best to start the new tank with new substrate. Even with meticulous regular cleaning you'll still get a big ammonia spike if you try to transfer the existing sand bed. I'd personally never reuse a sand bed, even after a thorough rinsing. I'd possible consider reusing a larger grain aragonite after a bleach soak to get rid of any remaining organic material that might cause an ammonia spike, and then a few days in fresh RO/DI but it's so much easier to start fresh and not have to worry about problems.

Again, not terrible advice, but I have done the rinse and re-use without any ammonia. If I lived somewhere I could easily buy new sand, I may have gone that route. If at all concerned, a good wash with fresh water should clean it up fine. Or get all new sand, it'll be shiny and, well, new

I re-used my sand,I just cleaned it very well until the water was clean, so all the debries are gone and put it back in the new tank without any issues..
