Deep Water Air Pumps AP-40
excellent air pump ; I have one on at all times. Has lasted all Spring, Summer, Fall, and Winter and still going strong.
I feel this air pump is doing such a good job keeping my Koi healthy that I purchased a back up identical pump. It has been on all winter and does a significantly better job at keeping an air hole for the fish than the 2 heaters I have in the pond. The heaters could not withstand the freezing temperatures of this winter and both failed. I am so thankful for this pump; it is working hard in long weeks of below freezing weather.I did purchase additional tubing and a bigger air stone to make it more effective.

This product bubbles the pond surface open
I have the pondmaster pumps on 5 of my customer's ponds in addition to a heater. It's the amount of air they produce that really keeps the
pond surface from icing over here in the Northeast. I'm in upstate NY and it's zero degrees. A heater alone does not keep the surface free of ice. I like using the pondmaster without the diffuser, just a flex air tube weighted down with a stone for maximum surface bubbles. You can insert this unit into a 5-gal. pail to protect it from being smothered in several feet of snow!

Excellent Air Pump
This air pump is exactly what we needed for our pond, to keep it open for our swans. It works great and I like that it can be rebuilt.

This pump is used every day and keeps on running!
I purchased this same model several years ago and it is still running -- I just purchased this pump as a second pump for during hot weather. Great quality!
