I got my new test kit today. My pool turn green while on vacation. Nothing crazy but enough that I couldn’t see the bottom of the deep end. While waiting for the kit I dumped in 5 gallons of liquid chlorine over 3 days. Saw some improvement day 1 and a lot today. Just a little cloudy still but blue and can’t see the bottom decently. I want to test the water. When I do the free chlorine test I used the 10ml mark. As soon as I put the first scoop in it turned dark pink. I put 16 drops of R-0871 and it didn’t change. Should I just keep putting in drops? Not sure what that means? TIA
