Hello all. I have recently bought two CO2 Art inline diffusers and although they work great I notice that my bubble count has to be increased to get the dropcheckers lime green. Did I perhaps install the wrong around or incorrectly. A fine mist covers the whole tank so its not flow related. Currently the CO2 inlet is on the end closest to the outflow towards the outflow lily pipe. I used the pamphlet that came with it as a guide. Any advice will be greatly appreciated as I was under the impression that I should use CO2 more efficiently with an inline.
