Aeration to Lower TA with a SWG

[Steve456]

I need to reduce my TA level. The best return for me to use to build a fountain/shower to aerate the water is near my SWG.

If I aerate the water while the SWG is operating will the Cl gas dissipate into the air?

Generally, the SWG will provide a lot of aeration with the mist it produces. You just have to adjust pH to 7.2 and let it rise again. Is that not fast enough for you?

I think Steve's question will the nearby aeration cause him to lose and chlorine. If so, the answer is no.

I believe I've heard that the gas is actually hydrogen.

However, I do wonder about aeration and chlorine. In the fish tank world, we would aerate tap water to drive off chlorine. Also carbon dioxide would go and pH would climb.

Aeration will lower the FC level, but the effect is so small, that you are unlikely to notice, even with lots of aeration. The difference compared to fish tanks is because swimming pools have much less surface area per gallon. The effects of aeration are a function of surface area, which is relatively small, so the effect is relatively slow, compared to what you would see in a fish tank.

Yes, small compared to a fish tank. Folks that did that were aerating 55 gal drum with hard rolling bubbles, looked like boiling. No comparison to pool but not unlike a spa.

Also in a pool with CYA most of the chlorine is bound to it and does not outgas.

Brilliant! So cool to have such smart people on this forum. Thanks for the education.
