Eshopps AEO11005 Overflow Boxes Pf-800 for Aquarium Tanks

Picture doesn't reflect the actual product. The PF-800 is a single inlet overflow box. Having said that, this thing works pretty great. I hear people say these are really loud. I can say it's almost quiet. My wife and I both removed how "quiet" the aquarium is with this new box. It gets a little unnerving. Now that I am used the quietness of our family room aquarium I must say something about this overflow box that I kind of figured out through trial and error. This overflow box has stopped siphoning two or three times. Depending on your set up this could be a big problem where all of you water from you sump could overflow your tank. What I figured out is depending on how you have it hanging on the tank could cause the U-Tube to be so deep (in the blox box inside your aquarium) that it's touching the bottom which causes it to lose siphon. I rounded out a soda bottle cap and put it under the tub u-section. The siphon works great now with no problems. I don't think it's necessarily a design issue but rather how i set my water level in the display tank. Maybe E-Shopps could provide a little shorter tube. I would recommend this box to anybody. Just be aware that if you are losing siphon please put something under the U-tube to lift off the bottom of the black box. Doesn't need a lot of lift. Just enough to allow the water to flow into the over flow.

Easy install, put on tank adjust black box up or down to control water level in tank. Start siphon ( I have found it is easy to put a piece of airline tubing up the pipe and start a siphon and then pull out). Was a little loud, I removed the black sponge and put a piece of airline tubing down the hole and it did the trick (thanks to a youtube video) I have it on a 75 gallon tank with a RIO Plus 2500 rated at 782gph pump. Works great!!!!

After reviewing many similar products, I took a leap of faith and purchased this unit to service a 90 gallon tank with 20 gallon sump. It was a little more expensive, but I decided I didn't want to deal with potential pitfalls of cheaper models. The unit came promptly; is made of substantially thick Plexiglas, has a appropriate size fill box that allows depth adjustments to vary water level and volume; siphon hose is also very sturdy. I have tested three times and the unit works well to "auto start" upon power failure or water level falling short. The unit is also very quiet, provided you make sure no bubble is in the siphon hose. A bubble causes drain at sump to sputter. Bubbles are easily removed by lowering the fill box to maximum level thereby increasing flow which pushed out bubble, then readjusting fill box once bubble escapes tubing. Negatives: the unit as indicated in picture, does not come equipped with a cover for back water unit as shown in some other models. I made my own but really not necessary. The drain attachment is a bit larger than my current piping to sump, and required an resizing adapter if you have similar issue. Though the fitting is larger than my requirements, I imagine it would service a much larger tank. Happy with purchase.

Unit came in great condition and was easy to install. Keep suction, even during water changes, and starts back up as soon as power is restored. Seems solid, a bit pricy for a few pieces of plastic. Solid 5 stars.

I don't know why anyone is having issues with this overflow unless they didn't read the description. I have it installed on my 40 ga breeder reef tank and it took maybe 15 min to get it up and going, but only because I washed it prior to putting it on due to the strong new acrylic smell. I will say the tube to suck the air out is a little bit too short if you can't get beside your aquarium, however, if you own an aquarium I'm sure you have plenty lying about so it wasn't a big deal. If you run into the issue of not being able to get all the air out of the u-tube, once you start up the pump and flow is going just wiggle the tube until the moving water pushes it out (shouldn't take more than 5 minutes depending on your return pump strength. If it seems to not be keeping up with your pump then you need to add a piece of tubing under the u-tube like I did because it means the bottom of the tube is too close to the bottom of the skimmer box (I included a picture of what I mean) I have a rio+ 2500 pump with a 4ft rise and am very sure I could use an even stronger pump with no issues.

Bulk head needed to be grinded down before I could thread anything onto it due to a lip at the bottom of the threads that was almost a half inch long. Smoke tube came cracked so I had to repair it with aquarium sealant. The black overflow box design is terrible with the wing nuts not having any room to adjust them so I moved them out. 1.25 inch bulk head is too big as well. Didn't have time to return it due to the fact I needed one now so I had to do my own modifications to make this thing work. Will never buy this product again nor would I recommend it and I will be replacing it soon.

This is a fantastic solution for those of us without drilled tanks. Currently running this on a 75gal and it works perfectly. I noticed that other reviewers have complained about noise, while there is a faint 'gurgling' sound i can barely hear it over all my other equipment so its a non-issue for me. Will definitely buy this again when i get my second tank up and running.

I use this on my small goldfish tank. I needed heavy water turnover and I got a great sump at an affordable price that worked very well with this unit. It was a little difficult at first since I kept having leaks where the gasket met the hole, but I got it to work eventually with lots of silicone and alcohol. So far it’s gotten my water crystal clear and works perfectly with my sump. No complaints. It is loud... but not so loud that its unnerving

El producto es bueno; sin embargo, lo malo es que llegó roto, ya no lo quise cambiar porque me urgía, pero se debe tener más cuidado con el traslado, porque es evidente que aventaron el producto y por eso se rompió.

product works excellent. tried a few blackout tests and it starts back up everytime, tube never empties so it keeps its siphon, excellent product.

perfect arrived fast works like a charm

Works great. The only that bothers me about this is its kinda noisy. Not a lot but its enough to notice it. Can be difficult to stop the sucking sound. If you perfect the flow going through, it will quiet down. No issues restarting with power outage.

Love the unit. U tube came broken. I hope that they will replace it.
