Does aerating water raise pH?

  1. I am using an Ecoplus Air-2 air pump that pumps air into my 5 gal reservoir. I am concerned that this volume is small enough for pH to rise significantly within a day or 2 and I will have to use a lot of pH down to constantly adjust the pH.
  2. Aerating is just for the purpose of moving the water around it shouldnt have any effect on the ph well it dosnt in mine anyways.
  3. Aeration cant really change the H+, OH- ratio - so no pH change.
    I see my pH creep up as the water is used and the nutes get more concentrated.
