Product Description

The SlimSkim Nano is a specially designed internal skimmer for nano and mini-reef aquariums. The SlimSkim's unique intake design will draw from the water's surface, reducing disgusting surface bio-slicks. Once inside, the energy-efficient venturi air pump adds countless small, uniform bubbles, perfect for capturing aquarium waste and carrying it to the adjustable collection cup. With its compact and sleek design, the SlimSkim Nano is the ideal addition to your nano tank.

Customers say

Customers like the skimmer's ability to produce good skimmate. They also say it works well and produces skim mate almost right away. However, some customers feel the vivarium is too large and takes up too much space. They dislike the motor and disagree on performance, noise, quality, ease of setup, and bubbles.

Customers are mixed about the bubbles produced by the vivarium. Some mention that it is very quiet and has zero micro bubbles, while others say that it produces a lot of micro bubble.

Great skimmer for nano's
5 Stars
Great skimmer for nano's
Awesome skimmer! Keep in mind, it takes up to 3 days to start producing foam due to the oils from manufacturing. This is common with all skimmers. It's quiet and well made. The magnetic suction cups are an awesome feature. I love the fact that I can place this in my JBJ30 Rimless AIO tank rear chamber and cannon see it from the front. It just tucks away.
