Bell Syphons in joined bins working fine

On the same day that we discovered the problem with the fish tank which has been rectified in the intervening week, we ran water into the joined bins that make up two grow tanks.  Three 27 gallon bins were joined with ABS pipe as a consolidated grow tank, draining with one bell syphon.  We made two sets and each performed very well.  Now that the fish tank is stable we are going ahead with adding expanded shale to the grow bins.  I have some seedlings growing in vermiculite in preparation for transplantation into the grow tanks.
