Fish Tank Of Water

Do not add fish.
Fish tank of water. It is usually the most overlooked parameter. A reverse osmosis system ranges anywhere from 50 to 300. In a saltwater tank your salt mix adds the essential salts and elements to the water. The filters need to be replaced periodically however.
Then test the water. This is also important if you are moving your fish. 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. Remember to let it stand for a minimum of 24 hours.
Introduce a few small hardy fish such as danios or livebearers. 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. 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.
That gives a true picture of the ph. Fish cannot tolerate sudden changes in ph. The new tank must have the same ph. Balancing your tank to the fish who live there is key to their health and safety.
3 even a change of 0 2 can result in stress or death if it occurs suddenly. 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.
