PPM vs MG/L (Anyone Know this stuff)?

[JD'sReef]

So real quick, I was never good with math and I am hoping one of you can lend me a helping hand. I am using an "Elos" KH test kit and arriving at a reading of 7dkh. With that I am using a Salfert CA test kit and getting 379ppm on that test.
My buffers are Seachem and they use a different measurement which is confusing me to an extent. My question is as follows!
If
-each 1/2TSP (teaspoon) of ALK buffer will raise my Alk by .025 meql
And
-each 1 TSP of CA buffer will raise my CA by .12 meql!
How much buffer do I need to added once a week, or how many dkh = meql and how manny ppm = meql. I use Bionic throughout the week, but would like to help the levels get back to a better starting poing on my Sunday tank Day.
Much Appreciation,
J.

How much buffer do I need to added once a week

First this is a loaded question, how much you need to add can not be determined from a single measurement, you need to measure a few days later, maybe even a week, to find out how much you actually use.

or how many dkh = meql and how manny ppm = meql

True!
I was able to determine that my KH consumption rate was 1meq a few months back, but maybe I asked this question wrong. I more just want to know if there is a direct Conversion/Relation between the measurements given from my test kits in comparison to my buffer solutions.
Sorry for the confusion,
J.

Ah gotcha, well the easiest way I've found, is simply use one of the reef chemistry calculators out there
http://reef.diesyst.com/chemcalc/chemcalc.html
and simply put in all your parameters, and lower your alkalinity (or calcium) by the consumption rate (1 meq/L as you figured out) and have the "desired" amount be what you now have, that will tell you how much product to use per day... assuming your consumption rate is accurate.

Thanks sfsuphysics,
I am going to look at this site today an try and bringing my advanced reefing skills to the next level.
Thanks again,
J

Just a quick one to say that if you have not tried the link posted above, get on it. I really like how the parameter calculator incorporates the buffer you are using for the tank.
Thanks All,
J.
