The acid base balance of the water measured as ph is the most frequent cause of fish stress which can ultimately lead to fish loss.
Fish tank of water.
Introduce a few small hardy fish such as danios or livebearers.
Immediate water changes and adding 1 3 teaspoons of sea salt to the aquarium water will help reduce the effects of nitrite toxicity.
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.
This is especially true of water from tanks in pet stores where rapid turn over of fish can introduce a disease into the water with no opportunity for the store employees to detect the disease.
A reverse osmosis system ranges anywhere from 50 to 300.
Remember to let it stand for a minimum of 24 hours.
Set up and fill the aquarium with water.
In a freshwater tank use a remineralizer like seachem equilibrium to restore the mineral balance.
Then test the water.
3 even a change of 0 2 can result in stress or death if it occurs suddenly.
The new tank must have the same ph.
Do not add fish.
Fish cannot tolerate sudden changes in ph.
This is also important if you are moving your fish.
Run the aquarium filter for at least 24 hours to ensure that all equipment is functioning properly and that the ideal temperature is reached.
The filters need to be replaced periodically however.
In a saltwater tank your salt mix adds the essential salts and elements to the water.
Check the water you have before you decide on the fish you are going to get.
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.
