To make a stock solution, you will use the following formula for Reef Reef Advantage Calcium™:

____(x)____ (amount you want to raise calcium each week) ÷ 12 ppm (amount that one standard dose raises calcium) = ____(a)____(how many doses you would need per 150 L to raise calcium by x)

______(a)_____(result (a) from above) × 5 g (standard amount of grams per 150L) = _____(b)______(amount of grams per 150 L needed to raise calcium by (x) ppm)

____y____(your tank volume) ÷ 150 L (standard dose volume) = ___(c)___ (amount of dose you need for (y))

___(b)___ (see (b) above) × ___(c)___(see (c) above) = ____(d)_____ per week

Divide by 7 to get daily amount

For your reference: The amount of Reef Advantage Calcium™ that we have dissolved successfully is 1tsp in 25-30 mL of liquid. That means that for 1 L of RO/DI water you should be able to successfully dissolve 33-40 tsp (165 g-200 g) of Reef Advantage Calcium™. These are only estimations based on our findings, and results may vary in a larger volume of water.
