This method seems to be ideal for systems that already have a high alk consumption rate.
For example, in one of my tanks, I have 0.5dkh/day consumption rate based on how much 2 part I dose. However, if I dosed saturated kalk based on my evaporation rate, my daily alk addition would be 1.3 dkh. Over the span of 1 week, holding all things constant, my alkalinity would have increased 5.6 dkh and in a month by 22.4dkh.
Unless the elevated ph triggers a near immediate ramp up in alkalinity consumption by my corals, I would be reaching alkalinity levels that most would consider tank suicide.
Perhaps a more disciplined way to approach this is to 1st dose at night to elevate your ph but making sure it won't exceed your daily alk consumption. Then over time when there is a compounding effect where slightly elevated ph increased alk consumption, then you increase your kalk dosing at night until you reach parity.
