Good deal... time to take a break from fretting.

If you do not have test kits to measure calcium and alkalinity, you should get them as soon as possible. Preferably before you start dosing any more additives.

The best rule is to never add what you cannot measure or test for. No matter what the product label, website, GARF, or anyone says, test first. No two tanks are the same, and there is no such thing as a 'one-size-fits-all' solution, recipe, remedy, or method in this hobby, well maybe water changes... but even that will vary. Not to knock GARF, they've come up with some great ideas, but the notion of a bullet-proof reef is a bit of a stretch, let's face it they may not turn a profit on paper but something has been keeping the light bills paid.

Fairly confident that after testing you will find that unless your reef is heavily stocked with calcium demanding animals and such (sounds like this is a very new tank so that should not be the case) that your salt mix will provide the needed calcium and trace elements with just periodic water changes, with very little to no additives needed. My observations thus far indicate this holds true for about 75% of the lightly stocked SW tanks, many other factors come into play for the 25% I'm excluding from my comment.
