MSJulian,

Well thanks to you proding me to investigate further it was the chloramines. Actually I should have known this as every time I pulled the cover of I got the smell of chlorine just before I swam.

So now I will pull the cover off at least an hour before I swim and run the skimmer only. That seemed to do the trick last night, no more stinging eyes. The pool cleaner will automated run in the day time.

Fortunately the trades winds normally blow at around 16 mph to 26 mph as I live 1000 ft up on the side of a mountain and they roll over the top and down my side. Sadly these winds are not as frequent as they once were due to climate change as a central warm high often blocks them from south of the Hawaiian Islands as the La Nina now occurs more frequently and last longer. This has another bad effect Vog from Kilauea Volcano rolls back up the island chain and sits paralyzed by lack of wind making the weather look more like downtown LA in the Smog. But this is only 5 days or so each month.

Also as mentioned 88 F is a little too high, 82 F to 84 F is more than comfortable. Although my neigbour likes 92 F with their solar panel but they are in their mid-70s.

Thank you and Aloha.
