RC...I would need elec to compress the air...and I can do that at the house...I was talking about on site at the pond...wouldn't need anything to get the air flowing other than the pressure in the tank to aerate the pond..(basically just brainstormin out loud here)...BGK, I was going by the pool on the way to air up the tractor tire...thought I would have a little fun with the 3 year old...pretty cool the fountain you can make...she thought that was a hoot...
