Pat,

Unplug the trisensor...is that the plug that goes into the cell?

Aeration - look at FAQ sticky under Alkalinity Subtopic

Solar Panels - I was thinking that some water with the bleach should be circulated up there to make sure that algae/'goo' up there gets some...is the 6 hours or so that it is hot enough for the thermostate to open the solar valve enough?

Thanks
