Lowering TA with Dry Acid Or Muriatic Acid

[TheG$]

So what effect would an in line "ozonotar" have on the aeration process? (In other words assume I need to Lower TA a lot but need to keep pH where she is now basically).

My assumption is, it is already performing that aeration to a large degree. But not knowing how the introduction of O3 may effect the offgas of Co2, I am not sure. Thoughts?

The ozone will get converted to oxygen gas rather quickly and will essentially outgas oxygen from the pool (and such oxygen bubbles will pull carbon dioxide from the pool) since it is already saturated in oxygen (from being in equilibrium with oxygen in the air). I do not know the rate of ozone generation in a typical ozonator so can't comment on how good it is at aeration compared to an SWG. You could certainly try the TA lowering process with the ozonator off and on at different times and compare the rate of TA lowering. It's clearly going to be better with it on than off -- I just don't know by how much.
