Review on 🐠 Eshopps AEO11005 Overflow Boxes Pf-800 - Improve Aquarium Tank SEO by Trent Kraft

I don't know why anyone would have trouble with this overflow unless they read the description. I installed it in my 40 gallon reef breeding tank and it took maybe 15 minutes to turn on but only because I washed it before putting it on due to the strong new acrylic smell. I would say the air intake pipe is too short if you can't get near your tank. However, if you have an aquarium, I'm sure you have a lot of stuff lying around, so it wasn't a big deal. . If you encounter the problem of not being able to pump all the air out of the U-tube, after starting the pump and flowing, simply rock the tube until the flowing water pushes it out (this should take no more than 5 minutes , depending on the strength of the return pump, if it seems your pump can't handle it you will need to fit a piece of tubing under the U tube like I did as it means the bottom of the tube is too close to it is the bottom of the skimmer box (I've attached a picture of what I mean) I have a Rio+ 2500 pump with 4ft stroke and I'm pretty sure I can easily use an even larger pump.
