Air line outside.

I had to try it ,went and got 25 feet of 1/4 inch I.D. hose and ran it to the window.
My ph has been 7.8 no matter what I try. Yesterday after the skimmer being feed outside air for two days I tested the ph . To my surprise 8.4 well looks like I am drilling a hole !

That's a nice gain!
Here is me forgetting to turn my skimmer back on one night. I remembered the next morning.
