WARNING! POND UV Rust Found

[Czynot]

I purchased this 55w Pond UV sterilizer from amazon and was using it for pass two months. It works great and I did not need to clean my glass as often.
Today I took it apart to do some cleaning. After removing the UV sleeve. I was in horror to see brown rust stain on the inside housing wall. Upon looking closely I found that they use stainless steel for the outer shell. I never think they would use metal to replace plastic for the shell.
That explains why my stylo and birds nest keep STN/Peeling.

wow. poor craftmanship indeed. perhaps this was made for freshwater only, bc in my experience its only a matter of time before any stainless steel rusts when in contact with saltwater.
