Give us some info on your tank setup. What's in it? How old? Last water change and what kinda salt you using.

Unless you're doing hard corals, which'll suck up the calcium, I'd tend to guess it's one of two things - 1) bad test kit, or 2) haven't done a water change in a long while. Most of us that don't have the hard corals get our calcium updates from PWCs.

Need to know alk level also. Further info can be read below.

The problem with the two part additives is that both the calcium and the alkalinity are raised when it could be one or the other.
I test for calcium, magnesium and alkalinity.
I keep the calcium at 450, the magnesium at 1300 and the alkalinity at 8.5-9.5
If the calcium is low I add kent turbo calcium boost;if the alkalinity is low I add kent reef boost and if the magnesium is off I add magnesium chloride(I forget the brand)

I agree with the above posts--you need to test before you dose.

i apologize i got confused i thought my ph at 8.8 is the same as aldalinity. I have learned something. I am sorry for my stupidity. I am not a chemist, however, i have recently learned that I need to be.

No problem, you don't have to be a detailed chemist but the bold links will help you get the basic chemicals down regarding maintaining a SW tank.

Don't continue with the B-ionic at this point. Two-part supplements are really intended to "maintain" your calcium/alkalinity levels at a good point - it's meant to replace what the corals are taking out.

You need to get your Ca levels up (probably by using Turbo Calcium) and stabilize your alkalinity before you start doing a two-part dose. As previously noted, you're going to need to know your alkalinity (either in dKH or meq/liter) before anyone can really tell you how to modify your tank chemistry. However, with Ca that low, water changes alone are not going to be enough to get your Ca up in the low 400s.

Once you know both your Ca and Alk, then check this article out...

Once you get your Ca/Alk levels where you want them, then you can start with the B-ionic again.
