Lesson learned..


The ring and gasket around the light had slowly disintegrated. The leak was there. It's been in there for many many years, but one reason for this is not keeping water balanced. Vinyl liner types are notorious for ph bounce, and needs to checked for that. If you need to increase ph, save some money and just get baking soda....sodium bicarbonate.

My water is usually looking fine, but I didn't check it as often as I should.

99 degree predicted high Friday? Money well spent. Although I hated it.
