1st saltwater tank. 1st batch of saltwater stored in 44g brute trash bin. Bin is new, I rinsed it out when I bought them but didn't scrub or use soap out of fear of leaving some contaminants. HW-Marinemix Reefer Salt Mix. Current batch has been in the bin ~8 days. When I open the lid, there is a bad smell, not room clearing but noticeable bad, I don't know what to relate it to. Any one else experience this? Anything to fear, toss the water? Did I miss some prep step for those bins?
