Ok, so about 2-3 weeks ago I made a 30ish gallons of fresh saltwater from my RODI mixed with Tropic Marin salt in my mixing "trashcan" with lid. Week 1 everything was fine but week 2 or 3 i started smelling something. I was very ammonia'y so I opened it up and sure enough there is the brownish black stuff growing in the bottom. It had the lid on it and smelled terrible. Has this happened to anyone else and figured out why, im perplexed?
