Today I will share with everyone how to make a Co2 tank for the aquarium (Safe and
simple)
The clip is for entertainment purposes only and for those who want to make their own
crafts and for those who do not have enough economic conditions to buy dedicated Co2
bottles
In fact, you should use dedicated Co2 cylinders to achieve higher efficiency. Because
manufacturers have created perfect products
Again - My clip is only entertaining
