You should have had calcium up above 400 ppm within just a couple days. Test, dose, wait 1 hour for mixing in the tank, then test again. Then use those numbers to calculate how much you need to add to raise calcium by 50 ppm. Add the difference so you get the calcium up 50 ppm today. The dosage information on the bottles are simply somewhere to start, they are not written in stone by any means.
