To add:

If you're finding that you're adding twice as much alk as calcium and you keep upping the amounts of each, I think you should first try dialing way back on the rate you dose alk. It seems counter intuitive, but if you're precipitating out large amounts of additive due to an imbalance, you're not likely going to see normal levels in one, and way high levels in the other, it will look like 'normal' levels of the one you're over-dosing, and low levels of the other.
