Sand

[coralosity351]

So im soon flipping everything to the 125 but should i get new live sand or dry sand? All the rock from the old tank will be moved over so will new dry sand cause a cycle?

that has examples happening and documented for what you are planning

it wont recycle unless you expose delicate animals to pent up waste stores. The bac in the live sand aren't the breakpoint in filtration for your tank, any normal amount of live rock we use will do it just fine, the sand goes above and beyond. like if someone hooks up nine canister filters to an already fine tank...those fill up with nitrifying bacteria, but when you pull them off the natural complements left in place were already good enough to prevent free ammonia. tanks with a tiny amnt of live rock might need something extra, but it would have to be a really small amnt...lr is very powerful.

rinsing your sand works I show it on the very last post there. most use all new sand...saves work, no chance of reintroducing detritus unrinsed, and we cover in the first post why you should pre rinse your live sand.
