Ive been bad about cleaning. Going to get rid of the whole tank. no water change since christmas, been replacinc evaperated water regularly. been at least 2 years since filter cleaning. about 1.5 inches of gravel, last vacuumed at christmas. I added water last night but forgot to add prime. could that cause the smell?
not worried about the tank, only 2 fish left. More worried about the safety of my family
