View Full Version : Rust-like buildup/film on carbon block after 24 hours

04/17/2008, 07:33 PM
I disinfected my entire RO system with a bleach solution (it's been far too long) and rinsed it several times before installing new filters and a membrane. After 24 hours, I'm see a weird buildup/film on the carbon block. I've never seen anything like this before.

Any comments/thoughts?
