ME Coral Ca Powder

[LouieP]

I have ME Coral Ca Powder and 16oz of powder makes 1 gal of Ca.

If I want to make 1000ml of solution
3,785ml per 1 gal of RODI

3,785ml/1000ml = 3.785

16oz of Ca Powder / 3.785 = 4.23oz of powder per 1,000ml of RODI

Is my math correct?

Is there any reason why you want to just make 1000ml? I think I would make the gallon and then just take 1000 ml from that gallon. And seal the rest for later use.

It is calcium chloride dihydrate. You can use this calculator for dosing:

I dont want a gal of Ca sitting around since I use a CaRx and need it for minor adjustments.

The math is correct, but I do not know what use it is, unless you are just trying to make a smaller batch of ME recipe and are using their dosing instructions.

It makes no difference what amount of RO/DI you dissolve it into. The calculator I posted will show what you need as a solid for any given rise.

Yes, I want a smaller batches since I use a CaRx on my 110gal DT and need it for minor adjustments. My coral QT is only 15 gals so im dosing maybe 1-2ml at this time.
