Ok so for those interested and if you ever face this issue through testing (because it was driving me nuts) that the length of the house to the outside was just too long and the skimmer didn't like it. The diameter was the same, the only thing that changed was the length - I'm sure there is some scientific explanation for you scientists out there. So, through testing, I made the intake from outside bigger and ran a 3/4" pvc pipe and a 3/4" tube into the co2 scrubber inlet, the outlet into the skimmer is 3/8". While the reading is still off (favoring inside air) by .3 to .4 the gap is now that much closer and the micro bubbles look much nicer in formation when sucking outside air than inside so obviously co2 is not the only driving factor there.
I'm able to keep ph now at 8.07 to 8.10 without lights. That may or may not change in a fish only system when I introduce lights, if it does I suspect it will be minimal since there is no photosynthesis going on (that's about the only aspect of biology I remember form my high school days, should of paid more attention).
Hopefully some of this data helps someone else down the line, I know this site has helped me a lot from the experiences shared by others of what does and doesn't work.
