To make brackish water, you add aquarium salt to tap. Do I de-chlorinate the tap beforehand? I'm just confused on how to make it.

Do not use plain aquarium salt or table salt. To make brackish water, you need marine salt. You will also need a hydrometer to measure specific gravity. A hydrometer can be found in the aquarium section of most pet stores They cost $15 or less. Depending on the species of fish you have, brackish water will need a SG between 1.005 and 1.010. One tablespoon of marine salt per gallon of water will create brackish water at the lower end of the SG range. Yes, you will need a conditioner to remove chlorine and chloramine before you add the marine salt.
