API kits are ok for ammonia and nitrate, but they really aren't that good for calcium and alkalinity. I'm doubtful your test kits are accurate, but have you been adding something with calcium in it?

What brand of salt are you using? What supplements are you adding?

In short, Coral Snow makes your skimmer work better, and may or may not help transport nutrients to your corals (depends who you believe).
