Solution not turning amber

Hello all.
I've bought MMS solution and HCL activator ready-made - exactly at the right quantities as set out in the guide.
However the mixing (activating) has only ever created a yellow colour. I did reach out to the seller who seemed surprised but issued a replacement set. However I'm still getting the yellow colour.
Does anyone have any thoughts, feedback, ideas about this?
I assume that I'm getting something from it but probably a lower dosage?
Many thanks, Zoe

Zoe, how many drops are you activating and how long are you activating? 

If only activation a 1 drop dose (1 drop of SCS + 1 drop of 4% HCl) you may not see an amber color. And, look through the activation glass from the side and not straight down. Making a 3 drop dose should show an amber color. 

Also, do not activate near a window as UV light will decrease CLO2 instantly. 

Do you make each hourly dose "fresh" or make an all-day bottle?
