Balling Method, NaCl free Salts dosage

[badstraw]

I got a few questions regarding the balling method.

I got a 95 gallon tank, I recently purchased a dosing pump to start dosing Ca, Kh and Mg.
I don't really want to buy an expensive calcium reactor, that's the reason why I decided to try this method to maintain the parameters at a constant level.

The benefits of using this method is that it supposed to be accurate in terms of dosing the exact amount of Ca, Kh and Mg in separate quantities according to the tank inhabitants and their needs (SPS,LPS,clams, etc) The really best part is that the method keeps the ionic balance between the elements.


The formula is:

147g of CaCl2-2H2O in 2 L of water
168g of NaHCO3 in 2 L of water
50 g of NaCl free salts and 34 g of magnesium chloride hexahydrate in 2 L of water

Dosage:

5ml of each mix per ppm loss per 100l of total volume.

Now according to the dosage I got a few questions..

My Parameters are:

nitrate: .85 (red sea pro test kit)
Phosphate: 0 hanna checker
Kh: 7.7 salifert
Mg: 1290 salifert
Ca: 380 salifert

How much would I add in ml of the third solution if my tank consumes more calcium than alkalinity?

How do I know how much I need to dose in ml to raise 50 ppm of Mg?

How much I need to dose in ml of ca to raise it 10 ppm?

With that information Im gonna be able to program my dosing pumps to start dosing on a daily basis..

I hope you guys can help me, Im a little bit confused with the numbers..

I would appreciate any help.

If the tank doesn't consume equal amounts of each part, then some additional source of calcium likely is present. Water changes can do that, in some cases, and pH buffers definitely will.

If you want to raise the magnesium, then dosing magnesium chloride by itself is the best approach. This calculator will help:

The calculator also provides doses for calcium chloride.

For tuning the amount of the solutions you've made, some daily alkalinity tests will provide the data. I'd test and dose at the same time every day for a while. You should get a good trend line fairly quickly.
