I have a Hagen Nutrafin DIY CO2 system set-up in my 20 gallon, and I'm still using the ladder that came with the system. I'm wondering if it would be worth it to shell out $5 for the glass diffuser especially if it does a better job of diffusing my CO2. The ladder is inconsistent in terms of diffusing the CO2. Plus, it takes up a lot of space on my back wall. Would anyone recommend going with the smaller glass diffuser?
