I'm still trying to come up with additional aeration methods. Here's what I have in my pool -
1. Spa spillway
About 2/3 of my return water flows into the attached spa and then spills over into the pool with about a 2 ft drop 18" wide spillway. Lots of air bubbles
2. Natural stone Waterfall
I have a separate pump which pulls water from the pool and sends it gurgling down a waterfall made of stones, boulders and cement. The pump actually splits the water with a three way valve so that about 2/3 goes to the waterfall and 1/3 to and eyeball return. This also produces good water circulation and lots if bubbles at the waterfall
3. Spa water aeration
One other method I can think of would be to run the spa jets on the water in the spa (no heater on) and let that put lots of air into the water and then switch over to pool mode a dump all that freshly aerated water (~1000 gal) into the pool.
4. [PROPOSED] Pool cooler / shower
On my bucket list of to do's is to take some ideas I've seen here on TFP and build a PVC shower/fountain using the eyeball return from the waterfall pump. I'll have to experiment with showers versus fountains but it should be a fun project.
Are there any hard numbers using pool math on how much you can drop the TA using acid/aeration? Or is it pretty much pool specific?
