I'm not understanding that calculation.
It is not hard to determine how much alk and calcium All for Reef adds from their info provided to resellers, even if it is written with some technical problems:
https://www.bulkreefsupply.com/all-for-reef-tropic-marin.html
Specifications (per 500 mL)
- Carbonate Hardness Concentration: 2,800 dKH
- Calcium Concentration: 20,000 mg Ca
- Magnesium Concentration: 950 mg Mg
Ignore the technical issues with that statement, one would most credibly interpret it to mean it is 40,000 ppm in calcium and 5600 ppm in alkalinity.
Thus, adding 0.1% of the tank volume boosts alk by 5.6 dKH and calcium by 40 ppm.
You can use this calculator and use the entry for Randy's Recipe #1, then multiply the amount needed for an alk boost by 0.91 and for a calcium boost by 0.93 since it is a little more potent than my two part.
