Advantages

Far infrared effect
This product is the far infrared super ceramics added, expensive gems, silicon ore, germanium and tourmaline. Because their materials choose strictly and far infrared ray releases anion, the wavelength of far infrared ray is 4-14 microns, and the emission rate is 0.78-0.9, therefore, it can enhance the immunity of the KOI and other aquarium fish. What’s more,the minerals dissolves out of ore let fish grow more healthy.
Super porosity characteristic
Adopt the special burning processing, with super vesicular structure inside the ring. And it exerts its long-term stable biological filter function, make microbial stationed in the interior of filtration material. 
This product can enlarge the area of effective bacterium, favors the reproducing of effective bacterium, enhance the dissolved oxygen of aquarium. It is regarded as the super filtration material, and it is considered as the improvement materials of natural environment. Ammonia removal capacity is perfect.
Neutral pH value
The far-infrared bacteria house is not made of calcium and as such it will never erode and thus does not need maintaining, the pH value is neutral, which could using for many kinds of tanks.
Wide application
It is suitable for both indoors and outdoors usage as it is specially designed to work effectively in various filtration systems such as pond filters, overhead filter, canister filters, wet and dry tricking Filters, internal and external overflew systems etc.
