Hanna DKH certified kit

[West1]

I purchased a DKH certified standard kit about 8 months ago by accident instead of reagents and this morning I tried to check my hanna 772 with them.

I'm getting a reading of 6.0-6.1 and I dont understand the reading I'm getting vs. The certificate acceptable results between 90 and 110ppm.

Cert Lot# SC0193/17
Exp 03/2020

Some help pls, tyvm!

Alkalinity can be read in three different units: meq/l, dKH, and ppm. Your checker reads in dKH. 6.1 dKH is 109.1 ppm :)

Nice,
What's the formula to get this ppm number?

Tyvm!

You don’t got the google out in Cali? :p

One meq/L = 2.8 dKH = 50 ppm

Who needs the Goog when we gots TheEngineer on Reef2Reef?

@TheEngineer has more applicable reef knowledge by far.
