ok, i see.
but how do you synch the water coming using syphon and the pump that flows water out.
you can't control the syphon, you could either get a stronger current from the syphon then u need and the pump won't keep up and u get over flowed.
or you can get a weak syphon and then the pump pumps too fast and gets dried out.
or is there something i don't understand?
