Mine is different..! Lol.. My colour chart for kh is yellow for overdose is urs orange?

[nicreef]

hmm reading urs i went to check mine. seems like DD made a mistake!!! no wonder my salifert and DD test kit for mg can have a difference of 100......

my picture chart (the harder copy) 0.32 is 1360. On paper 0.32 is 1460!!

Maybe different batch issue,bought mine around 4 months ago both soft and hard copy reading are the same.

So we use which one?

i think follow the lower 1...if you follow the lower reading for mg, it would match the readings from salifert too (at least for me)

Never feedback.. Don't know who to feedback..

Feedback to Reef Depot. They are our distributor for DD products
