No need for the bubble wand.
Actually when you get Co2, no need and it is counterproductive.
Without the Co2 it will at least keep the water with the same levels of Co2 as the surrounding air.
So use it if you want, but really doesn't have any benefit. Plants add Oxygen to the water.
Pitcus Cat, I have two and hate them. I really like the look, but they NEVER come out from under a rock and I mean NEVER, maybe when I am asleep, but never do they see the light of day.
You are on the border of low light to mid light. Once you add Co2, if you add a touch more light, you should be able to grow anything you want. You can do it in that light you have, but I think it requires more patients and skill to do so.
Think about adding one of these with the addition of the Co2 http://www.bigalsonline.com/StoreCat...hwater&offset=
Also, Add as many fast growing stem plants into the tank to help uptake nutrients and keep algae at Bay while the tank balances. Also, if your finances allow, don't wait for the Co2, get it as soon as you can, it will help you very much.
