How long can these shrimps live in a temporary setup?

[cf21]

I am currently about 4 weeks in to the cycling process for my 1/2 G. Had to remove and clean everything after contaminated sand (washed with tap water) killed all the shrimps. I am planning on adding a second batch once there is algae visible. I plan to acclimate and add one shrimp to the setup for a day or two to test if it is safe for them and avoid having all shrimps dead within a day. If that does happen, how long can these shrimps live with just the water that came from the seller? Would adding some crushed coral, lava rock, macroalgae disturb the water chemistry? Will probably house them in a spare tall glass vase until the original setup can be re-cycled.

It all depends on who the "seller" is. Our shrimp are packaged to survive in their shipping bags for weeks. But it's still best to get them into their tanks as soon as possible.
