i would not dose what i did not test for but at the same time, i would test for alk, cal and mag in a either a fish only or reef setup with liquid test kits and dose properly. personally would always do RO/DI water in reef/fishonly setups as well. i also prefer refractometers ( search ebay ) over hydrometers as they arnt much more money and are much more accurate IMO.
how deep is that sand? i suggest less then an inch or 4'' -6''
a sump? skimmer? lighting? flow? stocking plans?
looking like your off to a good start and welcome to the forums.
