Eshopps PF Nano Overflow Box - Up to 50 gal.

Don't forget to rinse everything before use

Product has conflicting information. Amazon product description says flow rate is 200 gph. The enclosed instruction and Eshopps web site say 100 gph. My pump is 150gph and it seems okay.

Product is made from sturdy Plexiglas. The U-tube has little scratch on the inside surface. It doesn't seem to affect the performance.

The bulkhead size is 1.25 in. I connect a corrugated washing machine hose ($9) from Home Depot to the bulkhead secured with a cramp.

Instructions do not have any diagram. You figure it yourself (come on Eshopps. Can't you hire an illustrator or graphic designer?)

No need to siphon! Simply connect the box with the U-tube and submerge the entire thing in the water. Ensure no air is inside the U-tube and the box. Raise is up slowly while keeping the water in the box. Hang it on the tank. Done!

In case of power goes off, the U-tube will self-start. I tested this. I just need to connect my pump with a swing valve so the water does not flow back to the sump.

Overflow box does not produce any noise.

Nice little owerflow but the "U" hose who goes over from the tank and in to the outside box was overbendt from the producer and broke when trying to fit it. I would prefer to have the adjusting screw at the bottom outside to be a bit longer or the "bridge" who lies over the glass to be a bit shorter, very few have 3 cm wide glass in a nanotank. Due to this I have to find someting extra to put between the glass and the adjusting screw to eliminate movement and fish gettin stuck behind the internal box.
