Review on 🐠 Eshopps AEO11005 Overflow Boxes Pf-800 - Improve Aquarium Tank SEO by Liz West

The image does not correspond to the actual product. The PF-800 is a single entry overflow box. Like I said, this thing works really well. I've heard people say they're very loud. I can say that it is almost silent. My wife and I both noticed how "quiet" the aquarium is with this new box. It's a little annoying. Now that I've settled into the stillness of our family tank, I have to say something about this overflow box, which I figured out through trial and error, so to speak. This overflow box stopped sucking two or three times. Depending on your setup, this can be a big problem where all the water from your sump could overflow your tank. I've found that depending on how you hang on the tank, the U-tube can be so deep (in a block box in your tank) that it touches the bottom, losing the siphon. I rounded off a soda bottle cap and placed it under the tub's U-shaped cutout. Now the siphon works perfectly, without any complaints. I don't think this is necessarily a design issue, but how I set the water level in the display basin. Maybe E-Shopps can offer a slightly shorter tube. I would recommend this box to anyone. Just note that if you lose the siphon, put something under the U-tube to raise the bottom of the black box. Doesn't require much lifting. Just enough for the water to drain into the overflow.
