Run the airline under that and let the co2 bubble into the upside down glass. Just make sure its well anchored or itll float away when enough co2 builds up. This way the co2 is trapped within the water and has more time to diffuse. Excess will work its way out of the glass and bubble up normally. Works wonders for me.
Could I Do it with this Shell?

take the shell out, shells arent good in a freshwater tank as the act as a bufferer that willr aise the ph of your tank randomly, ending up stressing your fish. You could use the bottom of your lego house as there are small grove like things there.

the lego house is a pretty good idea although I wouldnt rule out the idea of it floating off somewhere. While the shell can raise your pH and co2 will definitely lower it so it might not be such a bad idea to have it in there anyway. The shell would work just fine for the idea and would be much easier to pin down .

The Shell has been Majorly Cleaned.

It is probably clean but no matter what you do it will still buffer, it is not toxic to your fish, it just changes the water chemistry which can be stressfull to your fish, expesially your fry.

cleaning the shell doesn't make a difference as far the the pH is concerned. The shell will slowly dissolve and raise the pH and water hardness. But like I said the co2 is going to be lowering the pH anyway so the shell could double as a slight buffer.

What do u mean as to Buffer?

buffering is what keeps your water pH stable. otherwise it would almost constantly drop as fish waste was added to the water. shells naturally buffer the water to a higher pH due to the calcium they contain. carbon dioxide injection lowers the pH due to the formation of carbonic acid. The shell may somewhat help keep the pH from falling to a level undesirable for the fish.

but then again the shell might raise it past the desierable level since shells raise ph. I would still suggest the shot glass or lego house since it is safer.

while they are indeed safer I highly doubt that one shell is going to take the tank beyond the "desirable" range fast enough to harm the fish. In fact my main tank has a whole lot of old malaysian trumpet snail shell slowly breaking down and the pH hasnt deviated from 6.5 in more than 2 months of daily testing. His tank is also pretty crowded so the more he uses whats already in the tank as opposed to adding stuff the better. And i have a strong suspicion that the ol lego house will hold enough of the co2 and end up just floating on around the tank lol
