Overall, this box works as it should...once you start the siphon (which is not clearly stated in the instructions, I had to look it up online), the water moves from the in-tank box to the outer-tank box, flowing into the bulkhead and into your plumbing. I cut power to my system and restored it multiple times and the siphon has always maintained suction. However, E-Shopps should state that there is a MINIMUM GPH that this box can handle. Let me explain.
I purchased a smaller return pump as I didn't want the water flowing through my sump too fast. This has proven a challenge for the overflow box. Since the flow is slower, the in-tank box has a lower water level, and when water "overflows" into it, the water dropping to the lower level pushes bubbles to the bottom of the box...which are sucked up by the siphon. You see where I'm going with this. Every few days air has built up in the overflow tube, it's not moving as much water, and my display tank starts to fill up beyond where it should. I can easily correct this issue by getting a larger return pump to increase the GPH going into the overflox box, but I wish I would've known about this ahead of time. I think 100GPH is probably the minimum flow for this particular box.
+ Equipment is well-built, sturdy, and adjustable
+ Great size for smaller aquarium
+ Included filter catches big gunk in your tank
+ Maintains siphon even with loss of power
- Poor documentation on starting the siphon (found online instead)
- Lower water flow can cause air to build up in siphon
Overall, this is the best bargain you'll get when choosing a quality overflow box for your aquarium. I highly recommend it for anyone who does not have a pre-drilled tank. However, just be aware that there is also a minimum amount of water that needs to flow through the box for it to maintain a good siphon.
I ordered this to use in conjunction with the Eshopps nano refugium on my 33 gallon oceanic cube. I was surprised the amount of custom fabrication that was required to connect the two. Figured it would be plug and go.
