I don't acclimate: I set the salinity to accommodate the store/source/incoming fish and put them right on in, so there's no acclimatation-damage.
I prefer no sand or rock, because that's where ich hangs out between fishes. No cycle, just clean basic tank, with a pvc pipe to hide in. I don't medicate unless I have a diagnosis and a condition. Hypo if brought up safely to tank salinity is not a bad choice, either.
You adjust your salinity very slowly, over the 4 weeks of qt, and the fish has not been stressed or medicated for stuff he hasn't got, and he's not plunged from a bag into a fight against the tank bully. He eats, he sleeps in his pipe, and he becomes confident food will happen tomorrow too.
