3,12-18 hours u should leave it to filter through properlly

Answer 2

you need to wait a day for the chlorine and other chemicals to dissipate. conditioner will help but you still need to wait at least a day.

Answer 3

If you are using tap water, it needs to sit for at least 24 hours. Or you can use a dechlorniater which can be found at most pet stores that sell fish.  

Answer 4

You need to wait 24 hours after changing your tank before introducing fish into it. Then when you put the fish in don't take them right out of the bag. Let the bag float on the water for at least 10 minutes to give them time to get used to the change in temperature.

Answer 5

fill ur tank with water put water conditioner in it (fish conditioner)

and then you have to wait a whole 24 hours befor putting fish in

cause chemicals in water can actualy kill them

next time you get your fish keep them in a bag and put theme in the aquarium wait 15 minutes then open the bag and poor a little bit of the aquarium waterin the bag with the fish then gently put them in the aquarium. use water conditioner too remove chlorine and amonia (etc...) from tap water

if the tempeture is diffrent, and you put them in the water they might get in shock so wait 15 minutes befor you put the fish in the aquarium do this evry time you change the water and your fish will be fine.

keep your bag tho.
