Fish Tanks

We propose the perfect fish tanks for our customers considering size and the growth of the marine life they are caring for.

All our tanks are made in Japan to the exacting standards and high level of craftsmanship that Japan is known for around the world.

We have developed our own strict shipment system providing safety and certainty for our customers from manufacture all the way to shipping of the products.

Fishing Nets

Our fishing nets are very useful for collecting zooplankton, sorting young fish, and overlaying double layered plants.


Features and Effects

①BT-50 is able to dissolve gas efficiently than gas bubbles generated by air stone from existing air pump or gas bubbles from existing air pump or gas bubbles from ejector method by water pump and is able to generate fine and even bubbles (10-30μm).

For example, let the gas diameter generated from air stone  be 1mm(1,000μm) and the gas diameter generated from BT-50 be 30μm, then the surface area become 33 times, 37,000each in volume and in case of 10μm, it becomes 100 times of surface area and one million each of volume, contact area with liquid increases and gas dissolution rate becomes higher.

②These minute bubbles have flotation effect (pop-up separation) and the bubbles which absorb small particles in water (dust, residual food, excretory substance, etc.) are able to be popped-up to water surface by its ascending force.

③Not only air but also gas, such as oxygen and liquid are able to be self-inhalation and visual adjustment of feeding quantity is possible.

④Scale up is very easy by adding the parts.

⑤BT-50 is simply structured with very low power, high efficiency, less failure, and low cost.

⑥BT-50 weighs very light, compact in size, only water pump requires power, so the installation work is also easy.


Set discharge water volume approximately at 7L/min (0.5kgf/cm²) – approx. 20L/min(3kgf/cm²)

And gas:20cc-40cc/7L water volume/min~100cc-400cc/20L water volume/min
