Bad smells normaly come from waste. things like uneaten food, fish poop (more of a problem if your overstocked), dead or dying plant matter and even poor water circulation.

what type of substrate do you have ? sand can become smelly if you don't stir it up once in a while. a large water change and a good vacume of your substrate may help. be sure to remove any uneaten food and any dead parts of plants.

hope this helps.

What is the smell? Earthy, sulfur, fishy? If it is earthy, that is what a tank is supposed to smell like.

Hows your tap water? I know here in the desert it can get kind of funky at the end of the summer when the water levels are low and the algea starts dying off.

If you have well water then it might have high sulfur levels that would cause it to smell. If you don't have carbon in your filter you can try adding some or if you already have some then it may need to be changed.

One time, i fed the fish beef heart, and some of it did not get eaten. Talk about a rotten smell It didn't go away with a normal partial water change. After changing 30 or 40 percent of the water every other day for a week or more, the stink gradually decreased. Maybe the beef heart was rotten when i fed it. It certainly turned bad after a few days and may have killed some snails and other critters, thus increasing the odor.

You didn't say if the aquarium has a sand substrate. Sand can get pretty foul, especially when gas pockets develop. In any case, a bunch of partial water changes should take care of the problem. Most, but not all, of the substrate also needs a deep cleaning.

I know that you don't think that your fish tank is over populated, but I own a 125 gallon tank and I only have 6 gold fish and an oscar with two plecos.... and I refuse to put in any more because I think my tank is at it's limit.... if you can't get your tank smell under control, I would consider getting another tank and splitting your fish into the two tanks.... OR JUST A LARGER TANK FOR THEM ALL

Why do you have gold fish in a tank with an Oscar? An Oscar is a cichlid and they are tropical. Gold fish are a pond fish not meant for an aquarium and they are not tropical. You have fish with completely different water requirements. And yes you are overstocked! Every fish you have in that tank can exceed a foot in length making that 125 useless. A single gold fish needs up to 75 gallons and another 20 gallons for each additional gold fish. But you probably won't have to worry about them for long because Oscar will pick them apart if they don't die from insufficient space first!

I've kept multiple Oscars in tanks with goldfish before. Just because Oscars can be aggressive doesn't mean they are going to tear the goldfish apart, it simply means they like to have their space. His 125 is plenty fine for two Oscars and a goldfish. My piranha lives plenty fine in a 30 gallon tank with goldfish and plecos.

I have two 10" Oscars 4 5" cichlids 2 5" convicts 2 large pelcos and a 16" golden channel catfish in a 150 & everyone's happy I've had them all from the beginning and my Oscars are usually hand fed and petted aggressive yes but if they have their space they're very happy

Yeah im seeming to have the same problem. I have a musty smell in my fish tank and it smells up my room. Ive been doing water changes everyday for a week amd am constantly getting out poop and uneaten food. I believe the smell os coming from my filter. I rinsed it off with water from my fish tank during a pwc but it still smells. I dont know how to get rid of the smell.

You have too many fish; you will need to add new filters if you don't want to move them. Try a home-made Pump and bottle filter with filter floss and carbon. (Lots of Carbon) I would even try two or more bottle filters. You have a lot of fish, so you might want to start looking for a bigger tank. Try Petco; they may have a special on fish tank for $1 a gallon. I hope this help you and good luck.

I have a African Cichlid tank an I only put 4 Cichlids per 180 tank. So ur problem is u are overstocking without enough deniritafying bacteria to compensate for all that waste.

Wrong, your tank has plenty of room, his is a bit on the crowded side, but only the pleco would stink, I wouldnt listen to anyone who puts an oscar with a gold fish.



ANY WHO try to get some of the API bonding agent, it will get any particles to group together an be eatin or filtered.Or take the less traveled path because initially using this will make your entire house reek, but its called Microbe Lift, it adds good bacteria, and will level out the balances in a few days. 50 percent weekly changes,any one who tells you its ok to do a water change daily or every other day,probably would also put an oscar with goldfish.lol

A 150 long will inhabit 2in per gallon of cichlds, i have two peacocks, malawi cichlid, two blood parrots, a oscar and jack dempsey,a green terror, three convicts, a texan a firemouth and electric yelow, and in my 70 gallon, i have two bumble bees, two giraff cichlids, and a redtail shark.
For filteration on thee 70 i use a sun sun canister rated up to 105 gallons, and a p350 biowheel by marineland, which since thats my bedroom tank, and i like to sleep i unplug the penguin at night, my 150 gallon is using two emperor 400s biowheel. With a wave maker and many live plants as well as a crushed coral substrate. My 45 tal whiich houses my convict/texas hybrid fry only uses power heads on undergravel filtration. it all comes down to filter filter filter. weekly changes at 50 percent. a lot of these answers are really wanky.

I think ur pump is awesome. Do u mind sharing exactly how u did it. And do u only use that or is it extra? I have two pumps one cascade for 125 gallons and then an aquatop with sterilizer light and my 100 gallon tank still stinks and i constantly have to mess with it. I finally took out all the rocks but a few and have been doing water changes. But the electric bill is killin me and ur filter looks like it works great. The flow sucks on both mine. Yes I kno I have a freak pecan cichlid (thats is what we call him) Convict/peacock i think.. in the wrong tank. Hes just been there forever and i havent switched him to my other tank.

I have a 20'×2.5'×4' indoor koi aquarium which holds 20 Japanese koi. Very expensive, however they are my babies ages ranging from 14-22 months. After aquarium has been working with no problems, yesterday it went from smelling a little fishy to dead today. However all fish appear to be doing well as so is water balance in aquarium. .
