Sylvia has posted my drawing of bucket siphons, air pumps and tea makers at http://aquaponicscommunity.com/page/glenn-martinez-aquaponics-manual. Enjoy. Some of the designs are "patent pending" but only for manufacturing rights. Individuals, non-protits and educational are free to make their own devices for use. It just when you cross the line to manufacturing that we need an agreement. Enjoy, these devices…
