Yes!
That's an awesome filter for this size tank.

For CO2, a simple easy to use method is using the a small powerhead, ex: maxi jet 600-900 series.

Then do the modification for the needle wheel.

It's pretty easy to do. A lighter, heat a needle and poke small holes in the impeller blades.

Then bubble the CO2 directly into the powerhead suction side etc.

This produces a very fine mist.

Add CO2 only during the day, so put the solenoid and powerhead on a timer that also turns the lights on/off.

CO2 is by far the most troublesome of the things folks add to planted tanks.
And it creates many myths and issues for folks.

Never underestimate the CO2, it drives growth 10-20X faster and has the largest impact on growth and algae than anything else.

Best to have good CO2 with med to lower light. That makes it easy to dose and get good CO2 without algae.
