ASM G4X Ozone friendly?

I've read they are. I've also run ozone through mine with no problems.
 
Cast acrylic will not be affected by Ozone. But the plastic in the pump may be affected in the long term. Any butyl rubber will be as well. Most polymers will be affected but only if they are NOT cast. Casting creates a different chain in the polymer double chain. So if its extruded or injection molded, it will be affected. If its cast, it wont.

PVC is an exception. Well not really in our application. But an extreme amount of ozone will cause chlorine to actually precip out of chain. But you cant create that much ozone at home.

This all applies to ozone in gas form, in solution most will be safe.

For a first post - very informative - thanks!!!

Welcome to NJRC....come over to the other forums (general discussion) if you have a chance to introduce yourself. Or just keep on reading and post when ready...that much info - it'd be a shame to keep it all to yourself! ;)
 
Third generation Rohm & Haas geek, anything you need to know about plastics, polymers and their reaction to the environment or chemicals, I am you man.
 
General rule of thumb with ozone. Only things safe from breakdown is glass, stainless steel and teflon. All else will have different half lives of breakdown. Its just a matter of how much ozone with how much contact time with the materials in question's molecules.

Even though in this hobby we don't produce much, it is still causing a reaction with everything it comes in contact with. Its just a matter of getting it to come into contact with your target before it comes in contact with an unintentional victim.

When injecting into a skimmer, if the turbulence is being created on the outside wall of the skimmer, this would be bad. If the turbulence is in the center column before reversing direction, then this is where you want to inject.

To test, place your skimmer in a bucket with water, get it running, and put a few drops of food coloring in. if you see the color come up the center to the top then come down the sides, your in good shape. If you feed from a pump at the top, make sure its dumping right down the center and not down the sides first.

If all is well, you want to inject the ozone into this center column.

All this being said, if non of the above is true, its not going to cause a melt down. This will only ensure a longer life to your equipment.

One last note on ozone. If you are using this in an enclosed cabinet, do yourself a favor and vent the cabinet. Long term exposure is hazardous to your health!!! Most of us have our head stuck in the cabinet multiple times a day.
 
Ozone is O3, three atoms of Oxygen. It is an unstable gas. It is a great oxidizer, very reactive with other compounds. Used in an aquarium, it can react with hard metals, convert waste products and act as a disinfectant.

It is harmful to you health if you breath it. As little as 1ppm can cause a reaction. Red itchy eyes, headache and labored breathing.
