I mean when I shake it the bubbles stay there and I see a little bit of it moving through the tube with a water droplet
I don't know where you got your DIY info from OP. Put 2 cups of raw cane sugar and 1 tsp of yeast with 1 tsp baking soda in a 2 liter bottle, fill with lukewarm water, and shake til dissolved. CO2 should be going crazy in an hour or so. What you are using for a diffuser matters too. Some ceramics don't work under DIY pressure. I recommend a powerhead. You'll have to refill this recipe each week or so. I actually use two 2 liters with this mixture. And I don't use a bubble counter, I use a drop checker.
