Cloudy water in the aquarium can have several causes. The most likely ones are: This is the most likely reason for cloudy water in a tank which has only been set up for a day or two. Various gravel and sand substrates which are available for aquariums will tend to need some washing before they are used - the more they are prewashed, the less they will cloud the water (the gravel/sand can be washed by rinsing half a bucket full at a time, stirring it round and pouring away the water, repeat until the waterIf new substrate is the reason for the cloudy water, it should disappear in a day or two as the particles either settle or are filtered out. This appears as a greyish haze in the water. It is due to the explosive growth of bacteria, usually in a newly setup tank. It occurs because the bacterial population of the tank is not in balance with the level of waste nutrients. sort itself out as the tank matures - it should disappear more quickly if partial water changes (say 20%) are performed.

Also, avoid overfeeding (very important in a new tank), to help reduce the waste levels. Remove any uneaten food, decaying Note that the bacterial bloom will not cause any harm to the fish. This may also cause a greyish-white haze in the water. The causes may be complex, but it is more likely to occur in harder water which contains more minerals.

If you suspect that excessively hard and alkaline water may be the cause, investigate the pH and hardness of your tapwater and tank water. A short term haziness could also be caused by bubbles of gas in the water. This is less likely to occur if the water has been left to stand and aerate naturally for a while, and warm up to room temperature.

Ultra-violet (UV) sterilisers as part of the filtration system will also destroy floating algae cells, as well as

Another short term solution is to use a Diatom filter, which can remove very fine particles from the water and should cure the immediate problem. However, remember that the root cause (usually too much light/excess nutrients), needs to be tackled to prevent it returning. Note that if you are seeing an excessive amount of general particles in the water, it may mean that the tank requires more efficient mechanical filtration to remove particles - overfeeding or a heavy fish load will make this more likely. Aquarium stores often sell water clarifiers which help to clump particles together ('flocculents'), making them easier for the filter to remove. These may help to eliminate some of the above problems more quickly, but remember to address the possible cause, as well as the symptom.The first question you may have is: when is the water too dirty? short answer is: if you have any doubt, it is probably too dirty. casually look at the tank and see food particles or waste in the water,

A goldfish can't just leave the tank... if the water is dirty, they must literally live inIf conditions are bad enough, goldfish will sometimes try to free themselves by jumping out of the tank to their deaths. Dirty water holds less oxygen. Ammonia build-up can poison your fish (Goldfish produce a lot of ammonia). Dirty water can weaken your fish, and unseen food particles can nourish colonies of harmful bacteria.

On the other extreme, there is the tank which is "too clean." empty out all of the water and replace it with all new water from the faucet, you can cause other troubles for your fish, including stress because of the change in water quality. This is easy to avoid, however, and is described below./Getty Images It can be unsettling to watch your goldfish tank’s water become cloudy, especially considering the time and money you’ve invested in it. Tank water cloudiness is more than just a cosmetic concern; it can be a symptom of poor tank hygiene and might negatively affect the health of your fish. Fortunately, a little extra cleaning can help keep your tank water clear. Common Causes of Cloudiness A number of things can cause cloudy water in a goldfish tank. Some of those causes are innocent, but others require urgent attention to protect the health of your fish. A greenish cloud typically means an overgrowth of algae, while general fogginess points to a bacteria bloom.

Dirty water may also appear cloudy and take on a slight yellow or gray hue. Clearing the Tank Water If your cloudiness is caused by bacteria, you'll need to treat the entire tank with antibiotics recommended by your veterinarian. If you suspect algae overgrowth or a buildup of waste is contributing to the cloudiness, you must properly clean your tank to restore it to health. Begin by scraping away excess algae from the tank sides with an algae scraper, and then vacuum up any waste or food scraps accumulating on the floor of the tank. Finally, siphon out 20 percent of the tank water and replace it with fresh water that has been treated to remove chemicals and chlorine. If cloudiness persists, perform additional water changes every day or two until the tank is clear. Also, make sure your filter is of the right size and working properly. Keeping It Clear Keeping your goldfish tank clear requires a bit of work every day. Goldfish are known as messy eaters, and they produce a considerable amount of waste.

Make sure your filter is big enough for your tank size, and change the cartridge as soon as it becomes dirty. Make partial water changes at least once a week, depending on the size of your tank and the number of fish, and stop overfeeding your goldfish. You should only offer as much food as your fish can consume in 10 minutes. Anything extra makes its way to the bottom of your tank and contributes to cloudiness and odor. Use water conditioners, as needed, and invest in an algae eater to keep your tank walls clear. Considerations If your tank becomes cloudy despite routine maintenance, you may have too many fish crowded into your aquarium. While the general rule is one fish per gallon of water, goldfish often need more space than this, according to RSPCA Australia. Also, try moving your tank to a different location. Too much sunlight through a window can warm the tank's water and contribute to bacteria and algae growth. If your fish seem unwell or if you notice any problems in your tank in addition to cloudy water, consult your veterinarian for advice.
