how to start overflow siphon
when i first got my fuge i was confused as to how to get the thing started, i tried putting water in the u-tube, keeping my fingers over it, and a few other things, nothing worked just right, but i did find a way that works 100% perfict everytime.
my sump/fuge came with some pumps a 600gal and an 800 g/h well, the 800g/h pump like most tank pumps or powerheads came with suction cups, mine where large enough to fit on the ends of my u-tube, what i do now is put the u-tube under water inside my tank, let it fill with water, i get two suction cups place them on the ends of the tube while still underwater as to not let any air in, i then press down on the suction cups so they create a vacuum then i take it out of the water, place it in my overflow, and diy surface skimmer, and before i remove the suction cups, i start my sump to bring up the water level in the main tank, i turn off the water flow leading to my sump w/ the ball valve i installed and then remove the suction cups to the u-tube.
then i slowly open the ball valve on the pipe leading to my sump, this way i dont get any air build up inside of my u-tube untill i turn off my sump during feeding time.
i just wanted to share this with everyone and hope it helps out a guy because it really stumped me when i was first trying to get the whole thing started.
