The reading in the 10G low tech tank kept rising to 2700+ppm! Somethings wrong.
I deduced that the membrane is facing the outflow of the filter. I suppose CO2 kept going through but can get out through normal diffusion.

So I placed the membrane face down. PPMs are falling. Interesting. This will help in the design.
