calcium help

[bizoid]

i have a 75 gal reef tank with a lot of everything (x2yrs). my calcium was reeding @ 250. my test kit was old so i got another one. still reading 250. so i dosed with kalkwasser three different times, then with liquid reactor. my calcium is still @ 250. my mag. was @ 1200 so i added mag. it has been well over 24hrs and my calcium is still reading 250. the new kit is marine aqauriums. does anyone have a clue why i cant increase my calcium???? everything in the tank is doing ok, but not great.

What is your pH, Calcium, Alkalinity, & MG.
When you can you should also check the readings on a new batch of saltwater prior to adding it to your tank. Also try adding mg, then dKH buffer, then your calcium, and wait a few hours to test.
