Couple of questions,

A) It looks like your CO2 is just run through the airstone(?) and bubbles to the surface?

B) Have you tried or compared the results to setting it up so your bubbles get sucked up the uplift tube of your HOB filter?

C) Any idea what your CO2 saturation is?


I've been running mine so it gets mulched by the HOB but it is a wee bit annoying... so if a good quality airstone is sufficient even if its not quite as good that would be ok because if necessary I can run additional bottles to make up the difference.
