Home made Ladder diffusor

[xmamx]

Would this Ladder diffusor design work.

Heres a pic first of all:

To make it you could use any sort of clear large tube eg. gravel siphon tube and coil the airline tubing inside it upwards. As it sort of shows in my really badly drawn picture the CO2 enters the lower chamber and then floats up into the spiral tube (slower or faster depending on how many spirals you make) and hopefully disperses in the water. As displayed in the picture also the assembly is submerged in the water so water can freely flow through it.

Also a side question would the standard airline checkvalve put on the outlet of a yeast CO2 system make the CO2 bubbles come out in big bubbles once the pressure pushes through the check valve or will is continuously leak through the check valve?.

Thanks for you input.
