What Causes Cloudy Water In Fish Tanks?
Are you having trouble finding your fish in the fish tank due to cloudy water? There can be several different reasons for cloudy water in a fish tank, so let’s take a look at the most common ones. These are debris from new substrate, bacterial bloom, chemical imbalance, or even floating algae.
Most new rocks and decorations will cause cloudy water. If this is the case then your debris should settle and go away on it’s own in a couple of days. Before adding the next decorations or rocks it best to soak them in separate water to get all the loose dirt off before addingthem to your tank.
Another problem that can come from new fish tanks is a bacterial bloom. This can cause the water to have a haze and look rather gray. This can come from overfeeding the fish or dying plants.
A sure sign of a bacteria bloom is when your water is milky and has a very bad odor. Not all bacteria are bad but some bacteria blooms can be deadly to your fish. When the nutrient levels get extremely high the bacteria go ballistic and multiply rapidly.
Be sure to remove all dead or dying plants if you have a bacteria problem. If you are changing fifteen percent of your water and using a siphon to clean debris, this type of haze will not cause the fish harm. But it is essential that you get in under control quickly.
Another thing to look at is whether or not your fish are being overfed. This can also cause the water to get cloudy. Just check the bottom of the tank for leftover food – that would be a sure sign of overfeeding.
Fixing fish tank problems like cloudy water from algae can be a pain because it will be thick and green. One of the best ways to cut down on the amount of algae in a tank is by adding algae eating fish. Keeping your lights on for long periods will encourage algae growth as well as sunlight shining on the tank so make sure to watch the amount of lighting your tank gets to help prevent algae growth.
If none of the above helps you with fixing your cloudy water problems, you should follow with a test kit. The test kit will be used to check the ammonia and nitrate levels of your fish tank water.
Once you have checked the levels, the reading for a normal level for both the nitrate and ammonia is zero. If you have something other than zero then your water quality is bad.
What causes cloudy water in fish tanks with open or semi-open style tanks? Many times these style of tanks could possibly have a stopped up filter causing debris to cloud up your water.
If you are still not sure what is causing the cloudy water in your fish tank, don’t panic. As long as your water doesn’t seem extremely bad and your fish are acting fine, give it a little time. Sometimes if bacteria is the cause the bacteria will kill itself.
This is definitely not advice for all cases. If you are concerned about your fish you should probably remove them until you get your problem under control. It is extremely helpful to have a quarantine tank just for occasions such as these. Regular maintenance will also help you enjoy your fish tank without concern.

What causes a fresh water fish tank to get very cloudy very quickly?
The tank got cloudy in 2 days. I have 80 gallon tank, 2 pumps With filters and a "bubble" device. Can it get too much oxygen? Please help.
One 8" Goldfish that looks like a koi, One 6" goldfish, Onewhite goldfish One 10" Algea eater .
I clean the filters weekly.
What is cycling? The fish are 10 years old.

Edit: Its an ammonia spike. Ammonia is very toxic to fish. You need to change the water, not the filters. By changing the filters, you are killing off all of the beneficial bacteria. You need to get a test kit for ammonia (liquid drops, not strips). You then need to learn all you can about the nitrogen cycle in fish tanks.
As you start to fix this problem and the fish heal from the burns, you'll notice them getting black spots if you are doing everything right. Those black spots are where the fish were burned chemically. A lot of people in this situation are surprised when the whole fish turns black. They have no idea they've burned their fish this bad inside and out.

Make sure you are not over feeding your fish, you are cleaning the tank once a month, replacing the filters once a month and if any fish die you remove them right away. Take your water over to a local pet shop and they usually test your water for free. I wouldn't be concerned about having too much oxygen.

its a bacteria bloom. it will go away in a couple days — there isn't much you can do about it — just tough it out and it will go away.

It is a bacteria bloom. That's a good thing when you are cycling your tank. It is a bad thing if you already have fish. It happens when there is a lot of ammonia (fish waste) and bacteria shows up to eat it. Ammonia is a big problem for your fish. Too much will kill them. If you don't have a healthy colony of bacteria in the tank before you add the fish there is nowhere for the ammonia to go and it will quickly build up to toxic levels.
If you have fish in the tank you will need to do partial water changes each day until the tank is fully cycled. Your goal is to keep the ammonia and nitrite levels down enough low enough to keep the fish alive until the process is over. You will want to buy a test kit and monitor the ammonia level. This is the ammonia spike now, later you will have a nitrite spike (also harmful to your fish) and then a nitrate spike (not as bad). Once the ammonia and nitrite levels are at 0ppm and the nitrates are below 25ppm your tank will be fully cycled. There is a good chance you will lose some fish in the process. At this point it can't be helped.
