Thank you all so much, you are wonderful gentleman. I was looking at a post where esshup has his packed column and the guy from Ontario made one as well. It appears that when temperature reading were done the water actually cooled 7 degrees through the column, that's a lot of degrees! Then you have the degasssing and DO affect on the water, it's a win win.

So, drawing water from the bottom of my pond I can cool it, degass it, add DO to it. I could probably make this stacked column in a way that disguises what it is and maybe improve the aesthetics because my pond is visible by my front road. Need a good pump to suck the water from the bottom and maybe not need a compressor.

I just got a new pond, I made it twice because I aint so bright.
