9. The AquaMaxx Ws-1

This nano skimmer mimics the design of your larger protein skimmers that have performed pretty well for years. Don’t fix what’s not broken, right?

In terms of cleaning efficiency, the Ws-1 is probably as good as it can be when it comes to handling nanotanks. As long as you put it in a tank that holds less than 65 gallons, it will do its job with ease.

Not only that, but this is a nanoprotein skimmer that will last you a long time, too. AquaMaxx is a reliable manufacturer and since your nanotank won’t brave the skimmer, it will likely use it solidly before it needs to be replaced.

The main problem with this nano skimmer is that it has to be housed in a collection bin. This makes this impossible for many nano tank owners. One of the main reasons people get small tanks is primarily because of the convenience and limited space, which is why sinks are not very common.

However, if you have a receptacle with your nanotank and you want something that can easily remove organic materials, then you should definitely consider the Ws-1.
