air pump

[stroppy]

i was reading up on over wintering your pond and there was a bit about airpumps ..this man bought his pump indoors and fed the line back into his pond to help keep it warmer ...now i can do that as my pond is right by my window just thought i would share his idea with you

most decent air pumps can handle the cold. Mine stays right in my filter pit without any trouble.

But it certainly is possible to run the line indoors the way you describe. LOL!

i guess i didnt explain it too well in the first post ... i meant it helped to keep the water warmer because it would be warmer air not cold going into the pond :biggrin:

Cold water contains more oxygen than normal summer time water, I never run an air pump in winter.

Unless the tubing was insulated in some way, I would think the air would have chilled before it reached the pond.

yes, cold water has more oxygen than hot water--and stagnant water (even cold) is never more oxygenated than water being pumped with bubbles.

But, aeration in the winter serves two purposes: 1) to prevent/or keep a hole open in ice without the need for a heater; and, therefore, 2) allowing for degassing when said ice forms.

I choose to aerate in winter for all these reasons.
