Review: Easy to install, easy to maintain, easy on the ears. - Item arrived well packaged with no issues. It was very easy to set up. I am using this on a 40 gallon reef coupled with a Eheim Compact+ 2000. I have seen some confusion with some posts as to how to connect plumbing to the output of the overflow. You do not connect anything via the threads, this is just for the collar to secure the bulkhead to the unit. The hole will accept 1" pvc. You will have to cement this in with pvc cement. I then connected a 1" PVC union to the output so that I could easily remove the overflow for maintenance. I used the ESHOPPS 6ft 1" corrugated hose to to connect the overflow down into my 20 gallon sump. The EHEIM is running at full power and simple connected 1" braided vinyl tubing to a barbed to PVC adacpter. 3/4". I then fashioned a return with three 90 degree elbows not cementing the last one in the tank so that I could twist it to any direction I wanted in the tank. Now for the unit itself. Well built, clean, and few parts to keep things simple. The U tube is of a consistent size and provides plenty of flow. One end of the tube goes in the skimmer box, which it heigh adjustable and the other end goes in the box. There is a compartment in the box that keeps some water in it so that the siphon is not broken in the event of a power failure. I tested this numerous times and when the power was reapplied, it started right up. When starting the siphon for the first time, I just put some airline into the tube and lightly sucked out the air. As soon as the water falls over the U, the siphon starts. EASY. I made a gurgle buster in anticipation of a noisy drain but found that the stock tube with foam is actually very quiet. I have no issue with noise. Just a gently sound of moving water which I find relaxing. Looking at my current set up, I think I should have gotten a EHEIM compact+ 3000 as there is still room for more flow in this box. But that is not the products fault. One thing I would like to have seen is a lid for the overflow chamber as well as it being a dark acrylic to reduce algae growth. Same for the U tube but nothing that is a show stopper. I was spooked by these overflow boxes in terms of reliability and hearing doom and gloom posts on some forums. If you perform proper reef keeping maintenance, there are no issues. I think issues reported were from lacking maintenance. I recommend this fully if you do not want to drill your tank. I am glad I got over my fear from lack of knowledge about how these things work.
Review: Up and running in no time - I had a CPR Aquatics CS90 HOB overflow plus an Aqualifter. all worked well until the aqualifter lost power and the overflowing onto my hardwoods began. As the aqualifter is no longer available I had to find another solution. With this Eshopps, there is no need for the aqualifter. The 1"bulkhead was a seamless transition. The assembly was straightforward The siphon start was super easy, especially by filling the u-pipe all the way up with water and temporarily using Saran wrap as i set it in place. Though it was relatively quiet I still used my DIY Stockman Standpipe to make it even quieter

### ⭐⭐⭐⭐ Great product for the money.
*by A***D on March 16, 2015*

This overflow does exactly what is is supposed to do. I have had a problem with bubbles accumulating in the U-tube from where the water fell into the overflow box and made it into the U-tube, but this may be because my tank could have a higher rate of flow. It also makes a lot of noise at the down pipe. However, both of these problems can be fixed with minor modification. I put a sponge in the overflow box to slow the water a little before entering the U-tube(no more bubbles) and I added an extra piece of PVC at the down pipe and now it runs great. This is a great product for the money and I would highly recommended it for the clever reefer on a budget. Lost one star because it had to be modified.
