DI Storage and "Bladder" containers

[REEFGREENER]

Randy'
I was wondering if D/I water was too aggressive to use a "bladder" type storage container.
Second question:
Is there truly a differance in TCF membrane rejection rates.
(i.e. Hi-Flow, Ultra-High,etc.) My tds on muncipal supply is around 800 and I eat up alot of D/I .

You will likely get some plasticizer going into the water, but a little GAC will likely be able to get it back out.

I store RO/DI water in a 44 gallon Rubbermaid Brute trash can.

I don't really know much about the different brands and types of RO membranes. Perhaps others that do will chime in. :)
