Maybe. Depends on how well established the rest of your filter is. If the
filter media has been in place for a while, then I wouldn't worry about
removing the biowheel. Remember, lots of hang-on-the-back filters work just
fine without bio-wheels.

The bubble rate you have set sounds high to me for a 20 gal. I run just
slightly less and 1 bubble per second on my 55 gallon tank. but you have
the bio wheel which will help you to lose a lot of the co2 you inject. I
would suggest you remove it.

Watch your pH level closely initially and use this calculator to
calculate
your co2 level. Also watch for gasping fish - a sign of too much co2.

Thanks for the help. Looks like after several hours of this setup,
I've got - KH at 4d, PH at 6.9 for a CO2 level of nearly 15. I think
that's probably OK according to the chart on the link you gave me.
Question about the biowheel - if I take it out will I see a spike in
ammonia/nitrites?
