How are you using these "J" tubes?  If it is a simple "J" then it will lose

its prime and go empty as soon as the siphon action has dropped the tank

level to the inlet of the tube or when flow is too slow to keep air from

entering the outlet.  You must be adding an overflow box on the inlet of the

tube and somehow preventing air from entering the outlet?  Seems like when

you add all these devices it might be easier to drill the tanks.

I tried several designs that did not lose their prime (various modifications 
of Wright's design). However, over time they all were replaced by a bulkhead 
for one reason or another. The smaller diameter siphons plugged up with Java 
moss or peat moss or some other vegetative matter. Bottom line - a bulkhead has 
never failed, although the foam plug slows down after a while if peat moss is 
in the tank.
