Any suggestions on loop siphons in order to get them perfectly working? I have a small flood and drain system with two grow beds 36X24X8 and 100 gallon fish tank about to start my first cycling process! Just wondering if there were any hidden facts you must know to get loop siphons w/hoses right?

Apartment Aquaponics: I made a 8'X8' frame out of 2X6's covered with plasic with space rug on top (a large bowl per say); just wondering if anyone had a better idea to protect floor?
