I am using the EI dosing method on my 135gal tank. Water volume is about 120gallons so I enter that amount in Nutri-Calc for a general EI dosing recommendation.

My question is about Calcium & Magnesium dosing

I dose the following

CASO4 - Calcium Sulfate
MGSO4 - Magnesium Sulfate

Can someone please look at the snapshot of my Nutri-Calc setup and comment on if my Ca/Mg dosing is too little or too much?

Important

* my "20ppm" of Calcium is the result taken from Nutrafin test kit and is in CA2+ "total calcium" level. The level of Carbonate Hardness in CaCO3 according to the instructions is gotten from multiplying CA2+ X 2.5 = 50ppm in CaCO3.

I am confused about whether or not Nutri-Calc is expecting me to put my "Source PPM" as CA2+ ... OR ... CaCO3 ...




Please help me if you can!


Thanks
