I just tested my Alk using Salifert and it differs from my Hanna checker by about 1dKh. I was thinking of getting a third kit so I could get another reading.
Do you use just one kit to test your parameters or do you back it up with a second? Anyone else using multiple kits as a cross-check?
(This isn't a question about Hanna v Salifert )
