Q: What kind of water do you put in a fish tank?
A: Water to Use in Fish Tanks. It is recommended that purified mineral water be used instead of distilled water. Alternatively, tap water can be used, but it must be treated to remove chemicals that are potentially toxic to fish. Chlorine or chloramine is often added to tap water as a purifier, but such chemicals can damage the gills of fish.
Q: What kind of water should I use on a freshwater fish tank?
A: Since you have to add buffer back into the water every time before using it, you have to make sure you rebuff the water with the same hardness every time or your fish will be in shock or even die because of the sudden change. Tap water is the most recommended aquarium water of choice for freshwater fish.
Q: Do fish tanks need a filter?
A: If you can provide the right amount of biological filtration without the use of a filter, then your fish should be safe. So while a filter is not necessary for your fish tank, you could be limited to the amount and types of fish you will be able to keep.
