I only keep 10g stored for such a small tank. It's kept moving with a MJ. I went to top off the tank and noticed the RO/DI smells nasty. I was under the impression that water could be stored forever as long as it's kept moving.
Maybe this will help or just confuse you more.

How long was it stored? Is it kept dark?
Should not go bad. If it's really RO/DI then there is not really much of anything for bacteria to grow on. Should not matter if it's aerated or not.
Is it possible the bucket wasn't totally clean before you filled it?
Once your TDS monitor starts reading 2 you should be replacing your DI filter.Water in is at 149, RODI water out 8.
I THINK I found my problem with stinky water. I just grabbed one of the MJ used for circulating the stored ro/di and it STINKS! Guess it went bad? I've only been using it for about a month.
why are you circulating your stored ro/di?
