I'm talking about this one:

( A-175 Fluval 4 "Plus" Underwater Filter - 110 V )
I'm just wondering if using an underwater filter would reduce the agitation on the surface enough to keep enough
CO2 in the water to avoid using an external
CO2 setup.
Basically, I have two HOBs and whether I need to use
CO2 or not, am I going to have to discontinue use of them in order to grow some healthy plants. I'm not talking the status of "planted aquarium", but I'd like to be able to have enough green in the tank that the fish have something to swim around and hid amongst.
I've only been doing this a year, so I'm a little wary of the
CO2 since it could hurt the fish if not used correctly. I really can't afford some of the setups that folks have (for
CO2). Just trying to get as much education as I can so I can make an informed decision.
I'm trying to get the lighting up now - hoping to get some replies on the Nova T5's so I know what I would do for an enclosure (or if one is needed).
