i have a 180g and a 100g in my living room and i dont smell a thing. if i take the hood off and get right down to the water theres a kind of earthy type smell but its very faint. my 100g doesnt smell at all i dont think.
i do remember when i started out with a very hugely massively overstocked 10g goldfish tank that did stink the house out, so much so i was doing a water change every couple of days, still didnt stop it. turned out i wasnt cycled as i wasnt using dechlorinator and i was also over feeding as i liked to 'interact' with my fish. i still feel bad for those poor fish :uhoh:
