Top Grow Bed is Down!

The top grow bed is currently down.  Water is not making into the bed from the tank.  I believe there is an air leak in the fill line somewhere preventing the needed back pressure from being created for the water to make it up there.  I rode the motorcycle up to http://www.biggrowhydro.com/‘s retail store in Lake in the Hills, IL but they closed early for some reason, so I wan’t able to get new hose and fittings.  I think that when I get the bed working again I am going to try some strawberry’s and maybe some mint.  Has anyone grown either?  Any successes in an aquaponic or hydroponic system?
