effects of ozone on plastics

[jlinzmaier]

I'm getting an ozonizer within the next week. Heard many great things about them.

I've heard that the o3 is so reactive that it often breaks down the plastic of the skimmers it's injected into. I'm using an old coralife skimmer for my reactor so I'm not worried about the wear and tear and I've created a carbon chamber from PVC for around $10. The next thought that comes to mind is "Since ozone is so reactive it breaks down the plastic materials it touches, Is there any chance that as it's breaking down these plastics there are harmful waste products being released/leached from that plastic?"

Does anyone have any literature about the exact effects of o3 on the plastic skimmers it so often gets injected into????

I've read that article before and maybe I'm just not seeing it, but does Randy describe anywhere the incidental effects ozone has on the reaction chamber material (skimmers) and any unwanted byproducts that may cause?

Anyone have any info?

Hi jlinzmaier,
The ozone gets used up, or reacts with the water immediately upon entering the skimmer or reactor. All of the common reef filter construction materials are safe to use, with the exception of Nylon fittings. They turn brittle and break in no time, but, AFAIK, release no toxins.
The main thing you want to watch is your venturi or inlet fitting for cracking. That and always use ozone safe tubing like Norprene. Regular vinyl tubing will turn gummy.
HTH,
Chris
