I had similar concerns about the airline fitting and leaks so I came up with an alternative.
I found this grey fitting at my LFS but I found out later that they sell them at lowes too but not in the normal plumbing section, they had a whole other section several aisles over that had a ton of these grey fittings. well worth it if you ask me. I just used the right size for my tubing from my filter then added an adaptor and a compression fitting for the CO2 tubing. Keep in mind there will be a ton of pressure inside the reactor, the pressure from the pump plus the weight of the water if the thing is below the waterline in your aquarium which I'd assume it would be. This pressure is more than I ever figured it woudl be, I hooked up my reactor to my pump shortly after building it and the pressure made it explode at the PVC cement seams, I couldn't pull the thing apart for the life of me but I watched it explode under my fishtank and cause a huge mess... anyway the moral of the story is avoid any weak connections because there will be a lot of pressure involved here, but its a good thing, it helps dissolve the CO2 which is the point of it isn't it.
as far as the Clear pvc goes, its nice because you can see in but its pretty expensive so I opted to avoid it. I realized that if I were to build a reactor of this size using it even if all the fittings are white then it would cost more than just buying one so whats the point of DIYing it.
