Personally after feeding certain brand pellets I give a few hours for smell to go away never use carbon because if you properly maintain water parameters smell should go away. Only use carbon to remove meds.
Need Help With Fish Tank smelling

so its the carbon ok cause theres some in the hob filter catridge ill change tht out soon I have a canister with the bio in it already so i think it should be fine to just swap both out
If Im a little heavy handed with certain pellets I notice some stinky water. Especially when I had fed Hikari Massivore or Carnisticks
i thinks its the tilapia i fed my oscar any way i got a air freshener which got rid of the smell and did a water change and changed the carbon and it went pretty much away thx for the help
I have a tank full of bichir and feed tilapia all the time and never had smell. But if I overfed pellets I would. The two foods I mentioned would be the worst but Ive even had issues with Northfin Carnivore and Northfin cichlid formulas too. But the gravel vac and water changes help. My puffer fish does get a lot of raw items like krill, shrimp, etc. and it will on occasion get a smell.
idk why its not rotten or anything idk why but once i threw it in the tank it smelled bad maybe a piece went under a rock tht the fish didnt eat and it left a smell
A water change once per month on an oscar tank, is probably why it smells, and that you like to see them eat so the water is probably 50% fish urine and metabolism by-products.
I'd say you need minimum 50% water change once per week .
I personally would do more, I norma;;y do 30-40% every other day on tanks with large fish. I also think you are a bit light on filtration, when companies rate their filters they are rated foe a community of small fish like Bettas, gouramis and angels, not oscars. I'd filter much more , by adding 3 or 4 HOBs to the tank, especially with such a lax water change schedule.
