what makes a fish tank water fog?

Answer 1

Aquarium Water Problems
Q. My water is cloudy. How can I clear the water?
The cloudiness you are experiencing is probably one of two things.

First, overfeeding your fish can cloud your water as the uneaten food is allowed to decompose. At each feeding you should feed no more than what your fish can eat in one to two minutes. Overstocking the tank (too many fish) also can cause cloudy water. Excess waste, like excess food, gives off ammonia and nitrites. You should have 1 gallon of water per 1” of (mature) tropical fish. Have 3 gallons of water per 1” of goldfish. It is best to buy the largest aquarium you can afford. The larger the aquarium, the more waste your aquarium can handle before it becomes a problem to your fish.

Second, your aquarium could be experiencing what is known as “new tank syndrome.” When you set up a new aquarium or when you carry out a large water change, it is very natural for your water to become cloudy as part of the system’s normal biological cycle. The reasons for this are fluctuations in the nitrogen cycle, and the release of gasses in solution as the result of an increase in water temperature. A water change of 50% or more will help by restarting the cycle.

Have a pet store test your water or purchase a Tetra Laborett Test Kit. High ammonia and nitrites would indicate excess food or waste. A 25% water change will bring down these levels until you can fix the problem.

Also, be sure you are providing proper filtration for your pets

If your tank is new (less than 2 months old) it's probably still cycling - and this is caused by bacteria multiplying. These bacteria will convert the ammonia (toxic to fish) produced by your fish and extra food to nitrite (also toxic), then to nitrate. As long as there is more ammonia and nitrite than the fish can use, they'll multiply to take advantage of these (they are more or less the bacteria's food source). Once the bacteria have multiplied so they are using all the ammonia and nitrite produce, the reproduction will slow down and the cloudiness will go away. You can speed this up a little by raising the temperature in your tank - the bacteria will multiply faster, and reach the point where they're using all the ammonia and nitrite sooner. Until this happens, you need to do partial water changes to keep the ammonia and nitrite from getting too high.

The same thing will also happen if you use an antibiotic in the tank - these don't distinuish between bacteria as "good" or "bad", they kill all they can affect, and this may cause there to be too few bacteria to process these chemicals until they multiply back to their original level.

Some other possible causes are dust in new gravel (it should be rinsed before adding it to the tank), a free-floating algae inthe tank (this will cause green cloudy water), too much organic waste from old food, fish poo, dead plants (this will be yellowish-brown), or tannins leached from driftwood (this will be brown).

If it's a new tanks or you did a complete water change it's the bacteria cycle developing. Give it some time and it will clear up. This is to be expected with new tanks. If it's an older tank the bio cycle is out of whack. If you don't have a testing kit you can take a sample of your water into the pet store and they will check it for you for free. Then you'll know what you need to add to clear it up. I always keep not only charcoal in the filter but I also dump ammo chips in the bottom of it. This will help control the amount of ammonia in the tank.

Answer 4

Are you referring to the water becoming unclear? If so, this is usually an indicator that your nitrates are off. Do a 25% water change every 3 days for 2 weeks, and be careful to not overfeed the fish.

Answer 5

The cloudiness is the bacteria themselves. They are multiplying like crazy, trying to keep up with all the poison that is now circulating in your tank. Quit feeding your fish so much and don't buy so many fish next time.

Answer 6

Ammonia levels are high.
Usually weekly water changes of 15% or so will help to keep this in check, as well as your biological filtration system. But every once in a while elevated ammonia levels do occur and need to be promptly dealt with.

Answer 7

leftover food.

Answer 8

from it breathing.......?
