aeration and pH rise

[pypeke]

I think I misunderstood about aeration. Can someone clarify?

I thought I only had to worry about raising pH higher when the return eyeballs rippled the pool surface.

If they do NOT ripple the surface, and are pointed down or sideways, does the water flow under the surface also cause the pH to rise?

Thanks!

No. The aeration comes from the interaction of the water with the air. It needs to be rippling the surface or better yet spraying in the air.

thank you, so I did have it right. I thought maybe my pH rise was because of moving my return eyeballs down and to the side. pH has never been this high.

pH can read falsely high if the FC level is above 10.

Also, pH will always rise. Vigorous aeration just accelerates it. A couple excited kids having a splash fight might be enough.

FC is normal for my CYA. No one has been swimming since the kids and grandkids last Saturday.

What about toddlers in swim diapers? I have no idea if there is anything in one of those swim diapers that would raise the pH, but I am sure my grandson probably peed in the pool more than once! Does urine raise pH? I know it use more FC.
