Kent Turbo Calcium

[Reefreak]

I have not used this stuff before but I ordered some and there are NO directions other than how much to use in top off water. "I don't drip top off" I just need to increase calcium levels. Has anyone figured out how much Kent Turbo Calcium to use to increase X number of gallons by X PPM?
Mag. 1,350
Alk. 8
PH8.3
Cal. 390
Running calcium reactor.
I know I can start slow and test test test to figure it out but I was hoping someone has done that already. "lazy I guess"
