0 0 ppm mg l ammonia nh3 is toxic to fish.
Fish tank out of water.
Tank water evaporation is a normal part of the cycle in a fish tank.
More fish mean more waste and more food for the microbes causing the cloudy water.
Too many fish in your fish tank may also cause a rise in harmful ammonia and nitrites.
Experts do recommend the use of special solutions and water conditioners to make the tap water for your fish perfectly safe.
The water that is removed with the debris using the gravel vacuum is replaced with dechlorinated water which performs a water change in your aquarium.
Be sure the replacement water is the same temperature as your aquarium water.
Add activated carbon media to the filter whether loose or carbon pads.
Immediate water changes and adding 1 3 teaspoons of sea salt to the aquarium water will help reduce the effects of nitrite toxicity.
If you do not know the history of the tank and what the water conditions really are in this tank this can pose a risk of disease or chemical toxicity to your fish.
This can sometimes be helpful when setting up a new tank but it has many drawbacks.
To understand the problem think of your tank as a little ecosystem something like a tiny lake.
As the water evaporates the amount of water for your fish decreases which can make the water quality also decrease as more fish waste gets added to less water.
Look for the warning signs of nitrite poisoning in your fish tank such as poor appetite inactivity fish hanging out by the water filter outflow and brown colored gills.
These are toxic to fish.
Any time tap water is added to the aquarium a water conditioner must be used to remove any chlorine chloramine that is present.
It is excreted through the gill membranes of fish introducing nitrogen into the aquarium.
This provides added peace of mind as it ensures that all chemicals that could be harmful to your fish are properly removed before they are.
Aside from behavior clashes and stress for the fish themselves the tank conditions in an overstocked tank can often deteriorate to a toxic environment which can result in cloudy tank water.
However it can cause problems if there s too much evaporation too quickly.

Don t put too many fish in your fish tank.
Water from another aquarium is another possibility.
