Thank you!
I do have a drop test for chlorine and ph, which was consistent with the pool store tests. Also have strips which were not all consistent with store tests. I will order the Taylor as recommended. Right now, we're testing right about 7 for PH. Muratic went in 6 hours ago and filter has been on most of that time.

Hubby is worried about pump overheating while we are at work and burning out pump house to the ground. We've been running the pump when we're home but both work during the day. It gets really hot while running for long periods of time. Is this realistic or just a crazy paranoia?

Also - I may have been a little dramatic when I said the pool was black. It was more like a dark-roast coffee. I'm fairly certain it was iron and most was at the bottom of the pool at that point, hence the test that wasn't registering much. In the house our porcelain has an orange tinge to it where water sits.

Based on the current PH should I just start with the chlorine tomorrow night? What's the stopping point for the chlorine?? Thanks again!
