Description:
98% of the CO2 released by the bowl-type CO2 diffuser can be dissolved in water.
Small bubbles diffuse into the water, and aquatic plants can take in abundant CO2.
The high specific surface area ceramic is easily dissolved in water.
Because the CO2 diffuser is made of glass, it is unobtrusive in the aquarium and does not disturb the layout.

Feature:
High quality ceramic
Made of high quality glass
For 4 / 6mm CO2 tube

How to use:
Before use, be sure to soak all the ceramic, disc, tube or surface for at least 30 minutes.
To prevent breakage of the glass tube, wet it with water before inserting it into the silicone or rubber shoe.

Note:
I recommend the device of co2 that comes out under pressure.
Not suitable for air pump.

Cleaning method:
Use a fragrance-free, chlorine-based bleach and wash it when it is mossy or when the foam through the ceramic grows gradually.
(Caution: Always follow the bleach instruction manual and use it.)
Put water and bleach in a one-to-one ratio and mix well.
Then, soak in an aqueous solution of the entire portion to be cleaned for 1 to 4 hours (dipping time depends on the degree of contamination).
After that, please take out and wash well.
With the above cleaning method, all the stains will be gone and it will be clean like new.
