Ok so the ice is off the water temp is up to 36 on surface. I have two shallow air stations running 5-8 feet shallow. I have the one that is in one deep end at 12 feet running and has been running all winter. Water fall is running 10Am to 7Pm and dumps into the same area of the pond that all air stations are running.

Wondering when I should turn on our last air station in the other deep end at 16 feet. Would like to warm this up all even as soon as I can.

There is some water chemistry happening right now. In the mornings the water will have bubbles that last for a minute or two around the air stations in the morning and only in the morning. Not enough to make foam just enough to show me there is some chemical reaction happening over night.

My question is can I let the 16 foot air station go when surface temp is at 36 and ice only out completely for only a day?

Cheers Don.
