Again, thank you all for the replies.
I have been calling fountain aerator manufacturers today and got some useful information.
Scott aerator has a 2hp fountain aerator that puts out 110 gpm pump with an 8 inch intake, depending on which nozzle pattern installed. The intake tube extends about a 1.5 ft down from the bottom of the pump, just have to add a collar on that and put my pipe to the collar, that’s 15 ft of 8” pvc. He said they have never tried it, but in theory it should work, if not, just remove the pipe and run it the way it was manufactured, without the extension, it will aerate down around 6ft out of the box.
Then talked to Otterbine, their 2hp pumps will put out 210gpm, their intake pipe tapers from 6” to 8” (or vice versa) They also have one in their Gemini series that will put out 665gpm, but it only comes with one style nozzle pattern and I don’t care for the pattern of that nozzle.
Next was a Kasco, their inlet is the whole bottom of the fountain, no place to install an extension, if you could fabricate to the fountain, the pipe size would be about the size of a colvert and probably too heavy to keep the fountain floating, not to mention the bulkiness of handling it
Thanks
