Can any math wizards check my calculations?

I'm Looking into dosing Red Sea Trace Colors D (Bioactive Elements), which says to dose based on their Calcium+ uptake.
But I use Seachem Reef Advantage Calcium, specifically at a rate of 0.47tsp per day.

Seachem Reef Advantage says 5g (1 tsp) will raise the Ca level of 150 liters (40 gal) by 12ppm.
My utilization of 0.47tsp per day equates to 12ppm x 0.47tsp = 5.64ppm Ca uptake per day.

Red Sea Calcium+ Powder says 1g will raise the Ca level of 100 liters (25 gal) by 3.6ppm
Equates to 1.6g will raise the Ca level of 150 liters (40 gal) by 3.6ppm, or 0.4444g/ppm

So get to my 5.64ppm Ca uptake per day, but with Calcium+ instead of Reef Advantage Calcium, I would need 5.64ppm Ca uptake per day x 0.4444g/ppm = 2.51g Calcium+ powder

Red Sea Bioactive Elements says to dose 3.6ml for every 20g of Calcium+ powder, or 0.18ml/g
So I would need to dose 2.51g x 0.18ml/g = 0.452ml of Bioactive Elements per day.

What size is your tank?

Use this calculator to get the ppm calcium you dose per day using your specific tank size.

Thanks for the calculator! And for your post, it made me recheck my math based on values for my 160g net volume instead of 40g. The end result is the same since I'm dividing the uptake by 4, then multiplying the Calcium+ dosage by 4.

Specifically this:
Seachem Reef Advantage says 5g (1 tsp) will raise the Ca level of 150 liters (40 gal) by 12ppm.
My utilization of 0.47tsp per day equates to 12ppm x 0.47tsp = 5.64ppm Ca uptake per day.


That calculation would be true if my net volume were only 40 gal, but my net volume is 160 gal.
So I'd have to divide my 5.64ppm uptake per day by 4, to get 1.41ppm Ca uptake per day.


And this:
Red Sea Calcium+ Powder says 1g will raise the Ca level of 100 liters (25 gal) by 3.6ppm
Equates to 1.6g will raise the Ca level of 150 liters (40 gal) by 3.6ppm, or 0.4444g/ppm


I'd have to multiply those numbers by 4 to get to my 160 gal net volume.
So 6.4g will raise the Ca level of 160 gal by 3.6ppm, or 1.7778g/ppm.


So get to my 1.41ppm Ca uptake per day, but with Calcium+ instead of Reef Advantage Calcium, I would need 1.41ppm Ca uptake per day x 1.7778g/ppm = 2.51g Calcium+ powder
