More CO2 questions?

Yes, something like that, although I like this price better. For the price of those airstones, you might also get a bubble ladder like this one. Or just try how a cheap normal airstone works, first. They stand the test if the bubbles don't reach the water surface

Edit: Just have a look at this page, especially near the bottom, for ideas.

Thanks for much for your help Ulan that showed me just what I needed to see 
I think im going to do the bell diffuser. if im understanding it correctly anything that traps the bubbles under it will work as the "bell". So I will run the tube all the way to the bottom of the tank and then place a clear "bell" above the outlet of the tube to catch the bubbles. I will probably use the bottom half of a plastic soda bottle(will that work as the bell?) Im thinking I may then place a fake plant or try to grow a real plant on top of the bottle or balanced between the bottle and some drift wood to disguise the "bell"
Ok think that will work? if not i will just use those wooden ones you showed me

You could build a power diffuser. This will give you near 100% CO2 diffusion. All you need is a small water pump, gravel cleaner vacuum, and a luffa. What you can do is take the gravel vacuum cleaner and drill the check valve out of it. Then drill a hole on top of the gravel vacuum intake, make sure the hole is a bit smaller than the outside diameter of the CO2 tubing. Cut the tubing at a sharp angle and pull it through the small hole with a pair of needle nose pliers. Cut the tube that came with the gravel clean to length and slide it over the output of the pump. You can get luffas (spelled right? The bathtub scrubby things) at wal-mart for 99 cents. Take the tie off the luffa and use enough material that will fit tightly in the vacuum intake. Use the tie to hold the material together.
What this does is trap the CO2 bubbles in the intake while the pump pushes water into the chamber and constantly mixes and breaks up the bubbles. This will pay for it's self in long run because you'll get way more CO2 dissolved.

If you can live with the look, go aheadLucas Kane said:
. I read that the diffusion rate of a bell is about the same as the production rate of most DIY systems. If the diffusion is too low, you can still direct the stream from a powerhead towards the bell.Ok then I think im going with the bell system and it should look ok after im done hiding it lol
Thanks for all your help every one o will post a pic of the finished product lol not that it will look very good just to show you what I have.
Anyway thanks again I think you have answered all my question s about CO2..at least for now

I use a dispo airstone (pretty fine bubbles) placed under the output from my power filter - the waterfall motion keeps the bubbles in the water for quite a while (see stone & hose, left side of pic linked in my sig).
