I was given a "like new" pond water pump recently. Rated at something like 17,000 gph. Simple intake/discharge through 2" PVC pipe.
I plan to mount it in a protected area under my pier, lift the water 4-5' and blast it back into the pond to help with aeration.
Now here's my goofy question.. and yes, I have awakened at night and thought about this! At the (distal) discharge end, would it help if I added a short 45 degree angle to: shoot the water back into the pond with a splat, or a 45 upwards to sail the water through the air? Or just leave well enough alone..
You know you've caught "ponditis" when you ponder things like this!
