So I see a few thread about putting a diffused bubble under the intake of a HOB filter, I'm only now first doing CO2 of any kind, and decided to put a hole in my intake just large enough to insert the airline tubing from my DIY CO2 into. Am I going to be getting terrible diffusion?
It's on my 20L tank, and I have it set currently to ~1BPS. I have a drop checker, just no 4kdh solution yet so I'm just letting it go.
Solution is 600ml water/200g citric and 200/200 baking soda/water
