Does anyone know if PETG 3d printing filiament is ozone safe?

Not sure if this is the right forum or not...
Does anyone know if PETG is safe to use as a difuser when running the airline through an ozone generator? I was thinking about running it through my upflow algae scrubber. Also, do you think that would kill the algae in the scrubber if I did that? I found where Polyethylene is ozone safe but haven't found tests for Polyethylene terephthalate glycol. TIA!

According to what I found, PETG is very ozone resistant.

I looked at that before. Is PETG considered the same as PET? Thanks!

I'm not sure - you mentioned PETG so I only looked into that.

PETG is PET with Glycol added. It is more stable. I would worry more about PET/G off gassing by itself and killing fish with or without Ozone. I have a problem that my S/O loves to use an Ozone generator near my 3D printer and now all my prints are peeling up my PEI covered print surface, aka sticking way too much.

Ouch...
