treatments, heavy algaecide usage and lot of other efforts.

Yes, I do know ozone is unstable. But injecting ozone in the pool
water for a couple of weeks gets rid of that nasty vegetation. I had
not read it in advertizements, I can clearly see it in my own
backyard.

As you mentioned earlier, you are pumping the water through the ozone
injector. This kills bacteria and algae that come in direct contact with
the ozone. No problem with that. It obviously works.

Sure. But it also takes water a fraction of second to go past that injector
into the pool. That means most of ozone does make it into the pool itself
where it becomes oxygen and atomic oxigen that is extremely strong oxydizer.
It not only kills algae, bacteria and viruses; it also cleans water of
various organic contaminations.

I just took exception to your statement there was ozone in the water, and
explained why that was not true. The half-life of ozone in water is very
short, and it decreases with temperature.

Yeah, I didn't mean that pool's water is saturated with bubbling O3, I meant
it reaches some equilibrium where that constant sip of ozone is enough to
sustain it clean of further contamination. That's also how chlorine works in
the pool--you put a tablet in a floating chlorinator and it slowly releases
it into the water.

And unlike drinking water that is running water, pool is a big pond where
the same water stays all the time. It constantly circulates through the
filter, gets ozone etc. So one does _NOT_ have to pump lots of ozone to
instantly kill everything alive in the water. It's OK to put just enough
to kill those microorganisms faster than they multiply. Even a little bit
faster. There is no rush, it may take several weeks until pool environment
stabilises, that's OK. It's a long process to get the pool properly
balanced...

BTW, that ozone does not exclude chlorine usage. It just reduces it. And
they work very well together. One should've had to use so much chlorine to
kill algae that it would've been impossible to get near the pool without a
gas mask. And ozone alone can not kill everything, those ozone generators
are not powerful enough.
