3 things to be aware of:
1: Ozone oxidises manganese, iron and sulphur making them insoluble and unavailable to your plants. Therefore you might end up with deficiencies.
2. Ozone oxidises all bugs in the solution. It will sterilise everything including any beneficial bacteria present.
3. Since this is relatively unreported... nobody knows how much ozone is too much and when your plants might start to suffer
If you're aiming for a sterile environment then it might be worth a try... not many reports of it working though...
You can get them cheap on ebay... I actually bought one and if I get hit with root rot I'll be giving it a try... Hopefully won't have to!

Thanks loftygoals
I was thinking about keeping algae and other growing stuff out of the res. I'm doing a flood and drain in rock wool cubes and while it doesn't get to bad between res changes, it would be nice to keep it cleaner.
I have read about aerating with O3 and having it provide extra oxygen and keeping the res clean. I had not seen anything listing negative impacts. That's the reason I was asking.
anybody else?

Link doesn't work but here is the bottom line
Results
It has been more than two
years since the ozone
system was installed and it
continues to deliver positive
results.
Figure 2 shows the very clear
difference between the
original raw water and the
post-treatment water.
Hydrogen sulfide was
eliminated completely – from
60 ppm to zero ppm.
The ozone system was able
to dramatically reduce the
organic load in the water,
which had a direct
influence on the water’s
pH (lowered from 7.8 to 7.04) and ORP ( raised
from –177 mV to a +225
mV).
The significant changes to
the overall water quality
paved the way for vast
improvements in crop
production results.
Rejection rates of 40
percent were reduced to
less than 3 percent and
fertilizer costs have been
cut by at least 50 percent.
The interval from planting
to first harvest was
shortened by 28 days,
contributing to an
impressive increase in
total yield of more than
300 percent.
With improved yields and
reduced operating costs,
the grower’s return on
ozone system investment
was just six months.

Ozone would only be used to control unwanted microbial life. Ozone will destroy organic matter in your nutrients among other things.
Better options:
Always keep your nutrient solution low (68F is wonderful..don't go above 75F).
If you can't keep your temps down you need a water chiller. If your temps are high...do not add any organic additives (sea kelp, humic acid etc).
We've done 100's of rounds following these steps and it works everytime
