The new tank must have the same ph.
Fish tank of water.
Run the aquarium filter for at least 24 hours to ensure that all equipment is functioning properly and that the ideal temperature is reached.
Remember to let it stand for a minimum of 24 hours.
This is also important if you are moving your fish.
Balancing your tank to the fish who live there is key to their health and safety.
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.
It is usually the most overlooked parameter.
The filters need to be replaced periodically however.
Set up and fill the aquarium with water.
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.
Check the water you have before you decide on the fish you are going to get.
Introduce a few small hardy fish such as danios or livebearers.
Then test the water.
In a freshwater tank use a remineralizer like seachem equilibrium to restore the mineral balance.
A reverse osmosis system ranges anywhere from 50 to 300.
Fish cannot tolerate sudden changes in ph.
3 even a change of 0 2 can result in stress or death if it occurs suddenly.
That gives a true picture of the ph.
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.
