Ozone - Are there any benefits?

Hi, Newbie here. So I was originally planning on doing a salt water pool, but when I was getting estimates, one company told me that he prefers ozone. So I asked what that was and did some research. (I did not come across TFP at that time). Everything I read sounded great! Use less chemicals, water feels better, not hard on equipment like SWG. So I got the Del Ozone 40. I hired a pool service to maintain my pool for the start up and until I feel comfortable taking over and he told me that ozone doesn’t do anything. That’s when I dug deeper and found TFP. I read all the posts I could find on ozone which all more or less says it doesn’t do anything for residential pools. My question is, does it do anything beneficial? Even just a little? Like help kill chloramines which is one thing it’s supposed to do. There are so many sites saying how great ozone is, I want to believe at least some of it is true.

At least by finding this site, I will avoid the 2nd mistake of going the pool store route which was my plan. My TF-100 kit is on the way.
 
It helps *indoor* pools that don't benefit from the sun in burning off some combined chloramines (CCs). But it does nothing for person to person transmission of disease, so the pool still requires an approved sanitation chemical.

The sites that say how great they are are probably sites selling the equipment, right?

Good choice in getting that TF-100. That's my preferred test kit.

Welcome to TFP :) You've come to the right place for pool owners to learn good pool care.

The ozone and UV systems are the two biggest rip offs builders offer. I bought the UV system...
With indoor pools there are some benefits to those systems. For outdoor pools there really is no benefit.

Congrats on the new pool an new test kit!
 
Some of them were articles from news such as latimes.
Quick search gives me some article from 1999 from a guy named James Dulley. Quick search in to him also shows where he is promoting those stupid solar powered ionizers, which is rather funny. Ionizers are bad (copper is an awful trend in the pool industry that needs to go away), but the solar powered ones are not even good ionizers! So he is promoting both bad pool care advice, and a bad way to carry out his bad advice. Ah, good times. He is a home improvement author, I'm sure he is very intelligent but pools are not his expertise and his information is coming from someone most likely in the industry.

There is a lot of terrible information out there on pool care, even (especially) within the industry itself. A lot of it comes from outdated information passed down through service providers, but also bad information works its way through the grapevine from the manufacturers of various "alternatives". A person who on the surface seems a reliable 3rd party source often can trace back the information they are sharing to the manufacturer or seller.

I welcome you to TFP! The information shared here is largely based on well documented chemistry. We try very hard to always have solid evidence and data to back up what we say and I hope that you find what we share in the forum and in Pool School to be useful. And unfortunately no, I cannot say that the data backs up any claims that ozone is useful in an outdoor residential pool. CC's are burned off in sunlight and without a high bather load that you would find in a commercial or public pool the supplementary oxidation provided by ozone is really unnecessary and only goes to waste. On top of that, the amount of ozone produced by the typical residential model is quite underwhelming so even if there were a large bather load it would not be of much benefit.
