Thanks to its relatively small and low-energy motor, the Tunze 9001 is incredibly quiet and can run all night without bothering a soul. The only downside to this model is that the skimmer cup can be difficult to remove, making it harder to clean the skimmer. Nevertheless, this is a wonderful option for nano-sized reef aquariums and will quietly work throughout the day and night. Tunze 9002 Product Review In this product review and buyer’s guide, we’ll provide an in-depth look at both the Tunze 9001 and 9002 tank skimmers. We’ll examine their specs and discuss which types of tanks they are best suited for. By the end of this guide, you should have a clearer understanding of which skimmer best suits your needs. Tunze 9001 Product Review As most nano tanks under 40 gallons (181.8 L) can’t fit a lot of fish due to size limitations, most hobbyists can keep up with parameters through water changes. Because of this, protein skimmers don’t guarantee 100% waste removal, though other filtration can be used to make up for what they miss.

Nano aquariums have been growing in popularity and new equipment and technology are finally making it easier to have a slice of the ocean on your desk. During Interzoo, Tunze released multiple nano gadgets that turned heads and the Tunze 9001 DOC skimmer was one of them. With a small footprint, super efficient and extremely quiet, we knew we had to put one to the test. Most dissolved organic materials have an electrical charge and are hydrophilic which attracts them to the bubbles forming at the surface. Some factors can slow down this foam production, like oils introduced into the tank on hands or through some fish food ingredients. The Tunze 9002 is slightly larger than the 9001, but it still works on the same “Flash Skimming” principle. As its engine whirs, it pulls water into a small chamber and adds air to create a steady stream of foam. This foam collects scum before it can settle into the tank and then overflows into a skimmer cup that you can empty to prevent algae and protein build-up. In addition to regularly cleaning the skimmer cup, the entire skimmer should be cleaned about twice a year. Salt creep can be cleaned as needed. The Best Nano Protein SkimmersThus, a DOC skimmer for 1,000 liters (264 USgal.) should be used for a tank with a maximum content of approx. 600 liters (158 USgal.).

The only regular maintenance that protein skimmers need is to clean the waste that fills in the skimmer cup every week or two, though some hobbyists might need to clean theirs every few days.Protein skimmers can greatly help hobbyists keep their aquarium water parameters where they need to be. However, stability can often come from regular water maintenance in smaller tanks instead of additional equipment.
