Any guidance welcome

Looking at the strip, there are two together at the top (nitrite and nitrate?) then a single one marked in degrees, then two more together, one of which looks like pH and the other marked in degrees. Of the two marked in degrees, which is GH and which KH?



I'd go with the water company, they have expensive equipment rather than strips to test with.

from top to bottom it’s
No3
No2
GH
KH
pH
Cl2

So the strips say GH is 8dH. I'd ignore that and go with United Utilities.
