Hey guys, my problem is my tank smells really bad. Its kind if like a stale sweat smell. It first I thought it was the live plants but removed them and replaced them with plastic ones and it made a difference for a day.I eventually striped the tank back. Scrubbed it, cleaned the sand and ornaments, changed around 50% of the water (I know but the smell was unbearable). Less than 2 days later the smells back and i have not fed him yet so it cant be rotting food. Anyone have an ideas
