when i set up my fug, i put it right next to the tank at the same level and had one 1/2" pvc
pipe overflow conecting the two, the water would flow from the pump into the fuge then overflow to the tank. well i didn't feel safe with just 1 over flow so i built 3 overflows out of 3/4" pvc
no matter what i do i can only get 1 of the overflows working. ill start all three of them, come back a cupple of hours later and only one will work. im really stumped! any ideas on why there not working. if i take 2 out and leave one then it will work, but when i put it with the other two it will stop. im really confused.
