I have been using the same pool store for our readings. I just ordered a Taylor K-2006 test kit so I can begin to rule out errors in the testing.

Backwash early this morning was very green, like I've never seen before. Most of the green is now off the walls and were left with light staining in the shallow end bottom and the water is very cloudy / milky water.

Since I have well water, I have the water tested frequently by a professional lab. Last testing was done 4 weeks ago, No Copper. Prior to this year we have always had the water running thru a heater, so any previous years reading of copper were attributed to that, the heater was disconnected in early June.

At this point I want to get clear and balanced,,,let the staining fall where it may, and I'll basically start over again once I'm in a clean usable state,,,or next spring (which ever comes first)
