^^ Sounds good!
Well I just installed this NAG mini on my 6g (the other NAG I ordered is going to the 60-F). I used one of those glass U's connectors (also from China) to give the co2 tubing to come over the rim a cleaner look.
This is approx. 2 BPS from an Aquatek mini regulator. Overall, I'm pleased once again! This is not comparing two of the 'exact" NAG-Aqua diffusers, but hey, both perform well for the price -- certainly better than my UP Aqua diffuser!
