What kind of sand is in the tank?
I used Play sand from HomeDepot in a 40g tank and the "organic" makeup in the sand started to decompose in the tank... Horrendous odor... rotten eggs to rotten flesh... nasty...
Obviously I removed the sand.
I also have a 20g long with Tahitian moon sand that has never stunk going on 8 months now no snails or loaches....
