SRO XP-5000 EXT starting to haze/crack

[UP Hog Head]

I have a Reef Octopus SRO XP-5000 EXT and the cone has an area that has a crack/hazing. The skimmer is in my pantry and is never exposed to any harsh light or bumping. Any idea what could be causing this? Thanks

I have 3 RO skimmers in my fish room and the 2 SROs, a 5000 and 8000 look like new when I clean them up. They had ozone run through them for years. The 150 has been out of service 5 years, It looks new as well.
I am going to guess what you are seeing is from the materials it was made with when it was manufactured. I have seen other peoples skimmers that have done this and various causes are offered but there is no way to know what actually caused it , if anything.

Cleaning with hot water causes crazing.

I have clean mine with warm water and muriatic acid. I don't have patience to wait for hot.

Cleaning with hot water causes crazing.

Now that could be a possibility. I have used warm-hot water on it. The skimmer still works great though. I think I’ve been running it non stop for something like 8 years now. I just ordered a new impeller and a BB 5000 to have as a back up.

All my RO skimmers have run until I needed a bigger one.

i had a couple reef dynamics skimmers and one crazed with the other being fine for years. the crazed one worked fine too so i wouldn't worry.
Same happened to one of my old octo HOBs.

My best guess from what i've read is the process when the acrylic is manufactured.

The acrylic is usually heat treated (normalizing/annealing) in the process and once in a while something must be off and the acrylic gets a little too brittle.

Thank you all for the input. Sounds like I don’t need to worry. I’ll make sure the water isn’t too hot from now on.
