HDPE ribbon discolored?

[wizard13]

Is it normal for the material inside the ozone reactor to be slightly discolored? A little brownish/green or should it be virgin white like when I initially installed it? My Mutiny has been running for a couple of weeks and where the water pours down through the HDPE, it is becoming discolored. Please advise if this is normal. Thank you.

Yes, this is normal and harmless. It is due to oxidation byproducts that sometimes build up on the media. You can wipe it off if you take out the media, but in my experience, isn't worth the trouble. I also updated the ozone reactor instruction manual to this effect as well.

ok, thanks for the clarification. The color doesnt bother me, just wanted to make sure there wasn't something wrong with my setup.
