9 Best Nano Protein Skimmers With Excellent Cleaning Ability

Nano aquariums soak in popularity thanks to their affordability and convenience. These compact tanks can be placed nearly anywhere in your house. 

Despite their small size, it is essential to regularly maintain them and the water quality. Marine tanks benefit from a protein skimmer and so do nano aquariums. 

This post will compile a list of the best nano protein skimmers that can create outstanding cleaning performance. 

What Do Nano Protein Skimmers Do? 

Nano protein skimmers are created to eliminate dissolved organic carbon contaminants from the tank water.

Fish, inverts, algae, and natural biological processes discharge organic into the water. If these organic compounds remain in your tank, they will gradually decompose and be turned into ammonia, nitrate, phosphate, and other harmful substances. 

Nano protein skimmers work 24/7, wiping out dissolved and particulate organics. These skimmers will get rid of organic substances when they are released in the tank before decomposing. 

Why Nano Protein Skimmers Matters?

Aquatic research has indicated that there is a direct relation between the level of organic compounds in the tank and fish diseases.

A dirty fish tank is a breeding ground for detrimental microbes that will attack your inhabitants. Cleaning out dissolved organics helps reduce the organic load, which leads to fewer diseases for your fish and corals. 

Dissolved organics also produce a yellow tint. Turn off the tank light, look through the tank lengthwise, and you might notice the yellow coloration in the water. 

Blue light wavelengths, which are essential for small and large polyp stony corals, are captured by the dissolved organics. Using a nano protein skimmer will decrease these compounds and provide better light penetration through the water. 

What’s more, dissolved and particulate organics might cover and clog the surface and pores of filtration media. With fine nano protein skimmers, the filter media will get a longer lifespan and require less replacement. 

Moreover, the skimmers can mitigate an algae bloom. Eliminating the organics before they break down into algae-stimulating nutrients, you probably block algae from growing on the tank glass, live rock, or filter.

The IceCap K2-50 nano protein skimmer is a sump-mounted skimmer proper for reef tanks of between 40 and 80 gallons, depend on the bioload. 

The protein skimmer is made from solid PVC and acrylic components. It makes use of a “beer bottle” shaped skimmer body, lowering random bubble turbulence inside the skimmer. That can considerably increase the productive contact time between the water and microbubbles when it flows into the action chamber. 

The skimming process is implemented by an internally mounted DCAIR-700 skimmer pump, which can generate bubbles and forces water into the K2-50. 

Markedly, the skimmer’s footprint is small, with only 4.75 x 3.5 inches, thanks to the internal water pump and slender skimmer body. Therefore, you can flexibly position the skimmer inside the sump. 

What’s more, the unit comes with a pipeless side-mount outlet that reduces the bubbling, gurgling, and unstable water height. 

The skimmer cup is placed on the smaller side, but it can be fitted with a drain line to enhance the service intervals.

  • Surface suction for film elimination
  • Bubble-free outgoing water
  • Quiet operation

Cons

  • The mount might not work as expected. 

How to Maintain a Nano Protein Skimmer?

Due to the small sizes of nano protein skimmers, they tend to require little maintenance. There are several tips and tricks that ensure your skimmer works seamlessly and durably:

  • Clean the collection cup every single day because nano protein skimmers provide small collection cups. If you don’t do it regularly, you might end up with the collected waste turning back into the aquarium.
  • Remove debris from the intake pump frequently.
  • Do not scrub the inside of the skimmer to the collection cup too much. Cleaning these parts too often might require your skimmer to “break-in” again.
