smelly fish tank

hello my tank is smelling up my room. i checked ammonia nitrate and nitrite and they were all normal. i looked for anything dead in it and nothing is dead. i changed the water and it worked for a day and then went back to the same way. i have cleaned out the filter pads and it stayed the same. i have not added anything to the tank either. i dont know what else to do. my ph is at 6.8 to 7.0 if that has anything to do with it

What fish food are you using? I have noticed a smell sometimes when I feed NLS and Hikari. Be sure not to overfeed. Did you vacuum the gravel during the water change?

Look for hydrogen sulfide if it smells like rotten eggs.
do a deep gravel cleaning and see if there may be issues under the gravel (black spots)

Another thing to check if it is a fishy smell, look around the rim of the aquarium for any fish food that may be there. I had some get on the center brace of one of my aquariums. Two days latter it had the worst odor.

When my aquarium began to smell, adding carbon into my filters fillable filter cartrage seemed to help alot. (just ask my mom)
