CO2 vs air powered filter

I want to add more plants to one of my tanks - a 55 gallon. I'll need CO2 to grow at least a few of the plants I want, but I have an air powered DIY 2 liter fluidized filter in the tank. The main filter is a canister filter and I don't really NEED the fluidized filter (although I do love my fluidized and moving bed filters), but it does look cool and the main reason I kept it is because a few of my fish like playing in the bubbles lol. I'm a sucker for fish doing cute stuff :P

The filter is in the back corner and does cause a fair bit of surface agitation in that corner. If I put the CO2 in the opposite corner and maybe increase the output to about 6 bps instead of the 3 I have on my other tank this size, will it be ok or will I just be completely wasting my time and money by adding the CO2 with this filter still in the tank?

You would most likely be wasting a lot of CO2. Even an airstone can off gas CO2 relatively quickly, unless you are injecting it significantly faster.

A timer would be the ticket.
