I decided to add a yeast, sugar and baking soda diy co2 system and i am having a bit of an issue. I made the set up 2 days ago and it is producing co2, but i think something is not working properly.... i have the hagen ladder diffuser and i read that it may not diffuse the co2 very well so i took it out and put the tube directly into my filter intake.... the only issue is that the co2 is not a constant amount....for the last 2 days i can see the gas travel through the tube, and then a burst of it flies up the filter and i hear the air noise they make in the impeller....but then water rushes back into the tube and the whole process starts again...and i am under the impression that it should be a constant bubble per second or 2, not just a bunch of bubbles every 20 seconds. i attached a video...and it might be difficult to see but a look at the set up might help you all give me some advice, the sound is very quiet but you can see the gas travel up the tube and then shoot into the filter and then you can see that the level of air in the tube lowers after and the process begins again, any help would be awesome...thanks!
