Check the water you have before you decide on the fish you are going to get.
Fish tank of water.
In a saltwater tank your salt mix adds the essential salts and elements to the 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.
Set up and fill the aquarium with water.
In a freshwater tank use a remineralizer like seachem equilibrium to restore the mineral balance.
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.
Run the aquarium filter for at least 24 hours to ensure that all equipment is functioning properly and that the ideal temperature is reached.
Do not add fish.
Introduce a few small hardy fish such as danios or livebearers.
A reverse osmosis system ranges anywhere from 50 to 300.
Immediate water changes and adding 1 3 teaspoons of sea salt to the aquarium water will help reduce the effects of nitrite toxicity.
Remember to let it stand for a minimum of 24 hours.
3 even a change of 0 2 can result in stress or death if it occurs suddenly.
This is also important if you are moving your fish.
That gives a true picture of the ph.
Balancing your tank to the fish who live there is key to their health and safety.
Fish cannot tolerate sudden changes in ph.
It is usually the most overlooked parameter.
The new tank must have the same ph.
The filters need to be replaced periodically however.
