R/O water storage

[Mr. Fairy Wrasse]

Hi friends;
I store my R/O water in the usual rubbermaid type garbage container, and it is pumped out via an ATO top off system. My question is this- Does sitting R/O water stagnate or otherwise grow any sort of bacteria while it sits in the container. Sometimes I notice that the container, and hoses in it, are slimey to the touch.
