I am new here working on a design for my first aquaponics system wish you were closer I would gladly lend a hand. Might I suggest a kickstarter or project funding site of some sort? There are so many people it seems interested in this field and I cant imagine a state side school would go amiss. Maybe offer discounts on training or seminars etc etc to backers. Just a thought it gives people who would like to help an outlet to do so. Thank you and I love this site I have learned so much. BTW Badflash did you post that link to the 17mm liner you spoke of?
