Are you dosing by hand? Invest in a doser and you will wonder why you ever went so long without one. Bubble Magus just brought out a neat little doser where you buy a single digital "master" and you can buy "slaves" to daisy chain to it. I think the Master is a bit over $100 and the slaves are $75?? So for about $200 all in you could have a doser.
The amount you're going through isn't unusual. I don't like the API kit for calcium though (alkalinity one is fine), and much prefer either Elos or Salifert.
