I am sorry if I offended you. I made a mistake adding the algaecide and I accept that. Otherwise, I just considered my posts as "thinking out loud".

No one has a 6 way kit locally. I have a OTO/Phenol kit and the reading today is shown below.

I do not understand whether you prefer the HTH 6way over the K2006. I will have to order one either way. I will order what you recommend.
