I have a 32 gallon Brute trashcan for my saltwater reservoir. I only put RODI water and Instant Ocean Reef Crystals in it. I keep the lid on it when I am not getting water out. This lasts me about 1 month before I refill. I have rinsed and scrubbed it multiple times, but by the time I get to the bottom, it really starts to have a locker room, or smelly feet odor to it. Is that normal, what could be causing that?
