dosing advice

[jerzsky]

i want to make a diy dosing system. i thhink i have the design down, but im a little confused at how much to drip. i used the calculations that are on a bottle of brightwells, and this is what i got.

 

it says to take the daily calcium uptake per day and divide it by 37. then take that number and multiply it by the systems water volume. when i did this calculation i came up with an answer of 12.2

 

now what does that number mean?? is that the amount i need to drip per day....i dunno....im confused. any help would be greatly appreciated!!! thank you!!!
