what temp to close

what is the recommended water temperature to close at (i forgot)

60 for open/close. It's not exact as algae begins to slow its exponential growth near there. It will not hurt you to wait until 50 or open there. Daily demand is next to nothing at that point and a days dose will likely last a week.
