Your filters might need a good cleaning. Only do one at a time and leave the other one for about two weeks. Make sure to only use old tank water and keep the media wet when cleaning. I would also cut back on the feeding and see does that help. I only feed my fish every second day....It's never smelled good, but the hot weather I think makes it noticeable. Like I said unless I'm right over the tank I don't smell it. Just curious if anyone else has noticed this. I feed them only nls twice a day, I have the fluval 406 and emperor 400, and I change about 150% of water weekly. All fish are there and accounted for.
You should really need to change more than 50% a week
