New to saltwater tanks

Hello everyone, I'm new to the hobby and have a few questions as far as cycling my new 14g biocube tank. I've been cycling my tank for 5 days now and have been checking my salinity and doing my best to keep in the safe zone. I tested my water last night for the first time with the API reef master kit, and got 0ppm for phosphate, 0ppm for nitrate, 380ppm for calcium but im sure i screwed that one up and need to retest and lastly 11 drops of carbonate hardness at 196.9 ppm. I know myphospate and nitrate levels are good but i think my calcium is a little low and i don't know what my parameter for KH should be? Any tips for a newbie? Thanks
