Help testing calcium

[mmw64]

I just received Red Sea Reef foundation pro test kit. After starting with 1 ml of the titrant I reached the correct color on the card with 0.3 of the titrant left. Can someone please tell me what the calcium level is in my tank?

If you started with 1ml and ended/reached the color with .3 left, you used .7 ml of tritant. Refer back to the results card, which wants to know what was used, and your calcium is at 350.

This obviously assumes the test was performed correctly.
