Kamihata Kaido Daruma Protein Skimmer for Saltwater Fish

Purchased new in October 2025 and used for approximately 3 months. Still fully functional.
Naturally, there are some stains, but since any skimmer will get dirty after a few days of use, please consider it if you're not set on a brand new item. I've cleaned it with water as much as possible. There is no odor. Only the tube was too narrow to clean, so it has been replaced with a new one. Instruction manual included.

High-efficiency skimming with a Daruma structure!
This device generates fine bubbles within the unit, removing organic matter such as waste and mucus, which are causes of water deterioration, and other debris floating in the water.
This unit is designed for easy installation on the aquarium rim, requires no adjustment of flow rate or air volume, is less prone to over-skimming, and can stably remove concentrated waste.
Compact and highly efficient!
This size is suitable for 90cm and 120cm aquariums (depending on the number of inhabitants and feeding amount, it is recommended for use with one unit for aquariums up to 360L in combination with other filters, or up to 150L in a Berlin system).
●The Daruma structure inside the unit extends the contact time between bubbles and organic matter, providing high skimming effectiveness.
●No difficult adjustments are required. It is designed to easily remove concentrated waste and is less prone to over-skimming.
●Features a needle impeller that stably generates bubbles for extended periods.
●Compact design with the pump integrated coaxially with the skimmer.
●Hang-on type for immediate installation on your existing aquarium.
●Choose between hang-on type and internal filter tank installation.
●Reduces the risk of water leakage by using a submersible pump.
●The impeller uses ceramic bushings and shafts for excellent wear resistance.
●The submersible pump is equipped with a thermal protector.
●Increases dissolved oxygen concentration.
Supplies oxygen to saltwater aquariums, where dissolved oxygen levels tend to decrease compared to coral reef environments.
●Removes harmful organic matter using the power of bubbles.
Removes organic matter such as waste and secretions from fish and corals, leftover food, and bacteria. Expected benefits include improved water clarity, better condition of fish and corals, extended water change intervals and reduced algae due to reduced nitrate accumulation, increased success rate when establishing an aquarium, and reduced burden on biological filtration.
●Performs gas exchange in the aquarium water.
By volatilizing excess carbon dioxide, ammonia, hydrogen sulfide, etc., in the aquarium water into the air, a more favorable breeding environment can be created.
