I find this interesting -the owner's manual for my spa gives recommended levels for chemicals and it is quite different from the box of test strip recommendations.
Even different test kits show different recommended levels.
For instance , bromine 3-5 ppm vs 2-6
Chlorine 2-5 vs 2-4
pH 7.2-7.8 vs 7.2-7.5 or 7.4-7.6
Alkalinity 40-120 vs 80-120
Hardness 50-150 vs 100-400
Maybe this just shows it's not all that critical and there is a wide range of acceptable?
What is the correct value when testing for alklinity, pH, etc?

I would suggest you read Pool School - either use the link at the top of this page or download the eBook from Amazon, etc.
Strips are not a viable method of testing water. They are inaccurate and unreliable.
I suggest you follow the water chemistry levels suggested by this site.
Take care.

I have also used the drop kits.
i looked for a digital reader but couldn’t find one for bromine and even the $229 one I don’t think texted for alkalinity.
