Do you have to cycle NSW?

Hi just curious do you have to cycle NSW or can you just get it delivered or from LFS and it’s ready to add fish and coral?

The cycle is for the rock, sand and other filter material in your tank to build up bacteria/a biological process to convert ammonia (fish poop) into nitrate. The use of natural salt water could help speed up that process with beneficial bacteria (although that’s never been proven to my knowledge), but ultimately the cycle isn’t related to the water directly.
