I have a basic Taylor test kit... PH and Chlorine/Bromine and i just recently purchased a swimline/hydro tools drop test kit. Now I was testing my hot tub (bromine) and when I went to test my pH, it came out purple.. yes! purple!
I was like, man, the PH is off the charts, now, its one of those kits that require you to add one drop of something to get rid of the chlorine and then you add 5 drops of the phenol red... Now, I went to double check with my taylor kit, the taylor kit shows a perfect 7.5-7.6 so now I dont know which one to believe, any insights?
