How long should tap water be left to stand before it can be used for keeping fish?
Tap water that has been held and left to stand for 2-3 days can be used for keeping fish. In actual fish keeping, to keep the aquarium water clear and rich in oxygen, the aquarium needs to be changed frequently. In order not to change the water quality and temperature abruptly, the water change generally uses the method of mixing in water; do not replace all the water at once, so as to avoid the fish developing illnesses from not adapting to the water quality and temperature. If food residue and waste can be filtered out, changing one tenth of the water every day is enough.
