I definitely agree with the pressure being higher deeper in the pond...Of course I dont have a 13' tube to test it in either...I guess I could rig a container and pressurize it to 6 psi with air....
Mike, I left my number for the main guy to contact me, but i haven't heard from him yet. If they would guarantee it to be sealed or money back, I'd have no problem having it done...Of course if it really worked like they said, it should be selling like gold around here then....
I'm somewhat surprised that no one has chimed in with any personal experience with it yet...
