水草情迷

I am using the "ladder" shape diffuser
The one just like a ladder and the CO2 bubble will run round and round in the ladder and gradually dissolve into water
Actually this system is running in a low pressure system
And 細化器 is different
細化器 actually run in a high pressure condition
that means you need to build up a high pressure in the container before the CO2 can be squeezed out
that's why my system can last 1 month and yours don't

Actually i am using the CO2 diffuser of this system
For for CO2 contained, i use 1.5 L Plastic bottle

For the ingredient
i use 4 spoon (the small coffee spoon in Maxim Fastfood) of "bread yeast"
for sugar i use 1/2 lb plain sugar
I try to fill up the container to maxium level just left ~ 2 inch of space from the bottle opening

The system can keep on giving CO2 at about 1 bubble in every 4 sec for about 25 days
