I have a hydroponics book in which the author says that you can go up to 70 feet with the riverbed system and still get good nutrients/ferts at the end of the line ...... of course that's for hydroponics ...... I wonder if anyone has ever tested the limitations of a riverbed system with an aquaponics setup I suppose that would also depend on the amount of fish/size of fish tank, etc.

BTW Taylor, I like your 100 gallon setup ....... kinda what I need to be aiming for ....... are you going to drill holes in the PVC with a hole saw or use a skill saw and make square holes? Just trying to get a few ideas for something I'm planning
