Hagen bubble diffusers

[Jer-]

Hi

are the hagen made bubble ladder diffusers efficient? are they good at getting the CO2 into the tank and bringing the CO2 level to the ideal level?

thx

In a word yes. I have two units in my 34G which give me approx 25 mg/l CO2 - I use a DIY recipe though to get more output than the Nutrafin sachets.
