This is my first attempt at DIY CO2. I'm using a DIY mixture for my CO2 recipe (sugar to first line, 1/2 tsp yeast and warm water to second line) inside of a Nutrafin CO2 system- I was having issues with the bubble ladder so I decided to shove a piece of fine sponge in the end of the CO2 tubing. I'm getting some pretty fine bubbles. I'll be getting a glass nano diffuser in the mail within the next few days... How does this diffusion look for now?
I used a piece of cotton and just changed it once a week(when I made new yeast mixture) for like a month until i got a diffuser, it worked just fine. I didn't even use the whole cotton ball in that month.
