Will 1/4 inch outside airline to the skimmer make a difference to pH?

Run is 20 feet to the the outside. Ran a 1/4 inch OD rigid air line for a future set up.

Will this be large enough to provide any positive impact to pH of the tank?

Will it be too restrictive and leasen skimmer performance? (Octo Regal 200s)

I did not have much luck using that method. I grabbed an Ice Cap CO2 scrubber and ran it in line with my skimmer. Made an extremely tiny diff (.1 to .2) started dosing kalk and now I’m above 8.2^ and I was at 7.7 before.

Thank you. I will look into a co2 scrubber.

For such a long run I would recommend a three-quarter inch line. You can reduce it as you need to input into your CO2 scrubber. However just like others have stated in this thread it's not or you should not expect a significant difference with this method. I run a 1" line from outside then split it to feed 4 CO2 scrubber chambers and I've noticed only about 0.2 positive difference.
Where I gained the biggest difference was by introducing Kalkwsser as part of my alkalinity dosing.
It accounted for about a 0.5 improvement.
Moreover I can spread out the dosing overnight when my pH would typically drop below 7.8.
Now it does not drop below 8.1 at night and Max out at 8.31 during the day.

I ran a 3/8 inch hose to a 1/2 inch pvc pipe through the wall about 10 feet total. Raised my ph from 7.9 to 8.2. It depends on how much co2 is in your room. My skimmer also has a 3/8 inch air inlet. 1/4 inch would be too small for 20ft.

Thank you all. Line will be too small and not provide ny noticable help.

System is not set up but trying to get everthing ready for tank delivery in a few weeks.

I will just run the kalk reactor and maybe add a co2 scrubber if needed.
