Question about test kit

[7thheaven]

Hi I am using salifert test kit.

I think the kits are getting old, the level is not correct.

Is there any notice about using period(I am not sure what is it called)

in salifert? I can not find it in my manual.

thanks in advance~

Good question, Vince, Probably over 1yr. from purchase the tests could become faulted, though I'm just guessing as all biologicals denature with time. Bob

Why do you think it's not working properly?

Why do you think it's not working properly?

I am not sure but Yesterday I bought KH test kit (salifert) cause the quantity

of liquid that need to test KH is remained a little bit.

so I tested new one and old one and level is a little different

All of the Salifert test kit boxes that I have came with an expiration date label.

A nice Habib touch ...

Vince, do you notice a difference in color of the reagent in the old from the new? Bob

No Not Color, just number of KH is a little different.
I can not remember, so not sure of exact number. sorry~
