Should I run UV on my water change?

My BRS 4-stage RODI system is in my garage and runs directly into a 50g "wastewater" Rubbermaid trashcan and 30g "saltwater" trashcan. I've noticed a black ring around the inside of the saltwater can as I premix the saltwater and assume it to be bacteria of some kind. Could this be harmful to my corals?

I know that some corals are more susceptible to bacterial infection than others and that could pose risks should they succumb and die. I hate to throw out 25g of freshly mixed change water but for the sake of safety, I'm going to run the UV on this batch. I'll then "Clorox out" the trashcan before the next mix but was wondering if anyone else wondered about this and/or took steps to prevent bacteria that might be in the mix tubs?

I make it a point to rinse my rubbermaid with hot water after every water change. Been using the same bin for about two years without build up. However, I have read of several reports of brown growth in mixing bins. Some people say not to worry about. Still, if it were me I would do exactly what you are doing in terms of bleaching and cleaning the bin. Just because im a worry wart haha!

Thanks, Lizbeli! I'm definitely going to start washing it out between batches with a hose and some vinegar or bleach. Can't be too careful with a miniature ecosystem, not to mention the investment into these systems.

Black ring is probably mold.

LOL! Okay, well I've never heard of fungi making corals sick but that is good to know.
