What depth does the groundwater come in and what is the temp ? Is the circulator running ?
Since the pond is dug into the ground water table, the ground water enters the pond at all levels top to bottom. The ground water temperature @ 10 feet is in the range 46-52 year around. The ground water temperature at 6 inches is in the mid 70s, currently.
The circulator is in summer dry dock up in the warehouse. It is only used in the winter.
