Research DI resins and amines. Other things that cause noticeable odors at extremely low levels are water disinfected with chlorine dioxide when it reacts with new carpets and carpet glues and many forms of blue green algae like Geosmin and MIB, often when lakes or reservoirs turn over with temperature changes, down in the parts per billion they are so pungent.

I noticed some black spots like mold growing on the top of the container today. That might be my problem. I'm going to drain and wash tomorrow. What should I use to clean?

Top of the sides above the shut off level, not on the lid.

I would lower the water level and wipe it down with a rag wetted with a bleach solution of no more than a cap full or maybe two in a gallon of RO/DI water. Let it sit for a few minutes then wipe it a couple more times with straight RO/DI to dilute or remove the trace of chlorine. Fresh bleach is a very strong disinfectant, 30,000 to 50,000 parts per million chlorine so more is not better.

Fill up a cup of water directly from your ro/di unit and smell the water. If it smells like fish it has nothing to do with the storage container.

If its coming from your ro/di and the smell bothers you, your gonna have to wash and replace everthing. Bacteria somehow got into your unit and thrives because there is no chlorine in the water to kill it.
