I tested with an OTO test kit and got a low reading of chlorine (0.5), but at least there was a reading.

I haven't added any power powder plus since Monday evening, I turned the SWCG on to 60% yesterday, so that means it is generating something, right? Do you think I should still go ahead and shock with 11lbs of power powder plus?

Forgot to mention, my pH was reading 8.0
