If you are worried about high ca, that's not the salt you want to use. Typically, Oceanic is the highest calcium content (around 580) salt out there and the ca/alk balance is out of whack. Alk is very low (usually around 8-9 dKH) for such a high ca level. What is your alk testing at?

Here's a general guide on chemistry levels in different brand salts.

That's interesting that you said that on the Bucket it says my Calcium Should be about 480. But I am not really worried about my Calcium I did not know what would be to high for my Tank if anything if turns out to be that high it should help my corals grow especially if I start adding SPS corals. But I would have to check my Alk levels to see where I am at. The good this is my Mag should be High I should pick up those to test kits along with some others. I might just go out and get the whole Salifert Line of Test kits.

No... not necessarily. More calcium does not necessarily mean more growth.

Bingo. Once you start thinking about, or being concerned with Calcium, you really need to know your alkalinity levels. Calcium and alkalinity go hand in hand when it comes how your corals utilize it. I'll post some links when I get home tonight that may help out...

Kurt is right on.
You want to keep calcium between 380-450 ppm (having it higher does no good or no harm...to a point), alk between 7-11 dKH (both higher or lower can cause problems) and mag around 1300 ppm. Also, keep in mind that phosphate inhibits calcification, so if you have high phosphates it can/will prevent corals/coralline from growing. It all works hand in hand.

Here's the link to the RC Chemistry archives. You can find just about anything you may want to know there.

Yeah Oceanic it's that bad just got to give it a chance I am just switching over so I have to work the kinks out of it. If all goes well in the next couple weeks I will stay with it. But I have faith it will all work out fine.

As promised...

Here are some articles to make your head hurt:

And here's one that seems to make the light go on in a lot of people's heads:
