You might reconsider the ozonator.
To quote
@JoyfulNoise ....
Ozone reacts with chlorine on a molar basis of 1:1 - that is, one mole of ozone will react with one mole of chlorine and the two will neutralize one another. The reactions are very complicated and there are different reaction mechanisms but, in general, 1 mole of ozone will destroy one mole of chlorine.
Your ozone system likely will put out sufficient ozone to consume anything your SWG could create. So, if the ozone were to react fully with chlorine, your SWG would not be able to keep up with the ozone generator.
Now there are lots of assumption in the above with the biggest one being that all of the ozone reacts with all of the chlorine. It won’t. Part of the reason is that, while chlorine is highly soluble in water, ozone has almost no solubility. So only tiny fraction of the ozone dissolves in water and some of it will react with “stuff” other than chlorine. But, in general, ozone will create a chlorine demand.
In general, ozone is absolutely unnecessary in an outdoor residential swimming pool. Most people that have ozone systems realize that they cost more to maintain than they payback in any real sanitation.
