Once all the air is removed the airline tubing must be removed or submerged. You may be required to fill either the internal or external box with more water as the siphon is created. Replace the U-tube into the overflow making sure that the airline tubing is at the apex of the bend and using a pump like a Tom's Aqualifter to suck the air out of the tube until it is replaced with water. Remove the U-tube and place one end of the airline tubing into the U-tube. Start by filling the aquarium until water flows into the intake box, and then using a cup fill the external box with water until the U-tube end is covered. Just lower the overflow box onto your aquarium and then connect your favorite type of plumbing to the included 3/4" bulkhead.Ĭan be done with a 1-foot piece of airline tubing. Hang on back overflows do require more monitoring and safety precautions to be in place, but can be completely reliable if installed properly and maintained regularly. Installation only takes a couple of minutes, and the PF-Nano only requires 2.5" of clearance outside the tank to drain water down to a sump, refugium, or wet/dry filter. In most cases, we would recommend drilling your aquarium and using an internal overflow like the Eshopps Eclipse, but in some situations, a HOB style overflow may be the best option. Traditional overflows require you to drill holes in your aquarium where Eshopps PF HOB overflows use a siphon to draw water over the wall of the tank without any modifications to your aquarium. Adding a sump to a tank will allow you to hide equipment and while adding water volume making your tank more stable. DONT touch the box for 12 hours! you dont want to smudge the perfect seam! and since its a thin bead it will cure relatively quickly.Add an overflow to any aquarium with Eshopps PF series of hang on back overflows. Stand back and admire the invisible seam you just made and feel professional about it. remove tape while the silicone is still wet!Ĩ. you will get some on the tape, thats a good thing.ħ. press firmly and run your finger over the spills on the outside only. gently place the box back into position without touching the tape.Ħ. (remember this seam is under very little stress, so you dont need massive amounts of silicone)ĥ. take the overflow box and put a very limited bead of silicone on, just covering the edges of the box without spilling, go slow and steady to get the cleanest bead you can. get some painters tape or masking tape and using 3 pieces make a U shape just a little off the overflow box (you'll have to try several times, but its ok be patient youll get it.)Ĥ. place the overflow box in position you wantģ. lay the tank flat with the glass hole on the ground.Ģ. Have a look at the picture, you cant see any silicone, here is how i did it:ġ. On the side note, since this seam is visible you probably want to do a good job of it. And as far as I know, silicone provides best water tight seals. So keeping this in mind, that the acrylic to glass silicone joint would not be under any tensile stress, all you need to do is provide a seal to stop water rushing into the overflow box thru the seams and draining your tank to the bulkhead level when the power goes out. I used ge1 silicone, why did I go with silicone? its because, if you think about it once your tank is filled the water weight is actually pushing the overflow box towards the glass holding it in place (So basically what RK_tek said, im going to have to disagree with VABumpkin about the flowing water and the inflow pushing, you should be worrying more about the water pushing up and pushing against the overflow box) There will not be any force pulling the overflow box away from the glass, well.only if the tank is empty. Ill chime in since I just installed mine, check below.
