Ca & KH results

[jasond]

I recieved my J&L order, and tried out the Elos test kits I ordered. Results are:

Ca: 250
dKH 9
PH: 8.23

For Calcium I have "Kent Marine Concentrated Liquid Calcium" and Salifert KH and pH buffer.

Judging from what I was able to dig up, my Ca is fairly low, should be around 400, and dKH might be a tad high. Should I dose Ca every day and and not the KH buffer, and just monitor that the Alkalinity&pH dont fall? Or when I dose Ca should I always dose the KH&Ph?

Sorry for the rookie questions, I know where the numbers are supposed to be, just not sure what the safest way to get them there!

Thanks in advance.
