STOP STALKING ME (EVERYBODY LOVES CHRIST) guy!!!! Your just a old man that is 31 and gay literaly... as you mentioned and lives at home with no job and likes to pretend you can get some penis. Just leave me alone.

Answer 1

Where did people get the idea they should leave the fish in the bag for 24 or 30 hours??? OMG. While the fish are hanging out in the bag, they are adding waste to the tiny amount of water they are in. Would you like to hang out in your own waste for that long?? This greatly increases the chances of the fish getting sick or dying. It would be better to throw them into the uncycled water! You should not buy the fish until the tank is ready for them and then float the bag for an hour at most to allow the temperature in the bag to be about the same as the temperature in the tank.

But as Nuna already said, you can let it sit for 10 years and it wouldn't matter. However, you should take your new tank home, rinse it and the gravel and any decorations, set it up with all the equipment and let it sit at least 24 hours. Watch to be sure there are no leaks and to ensure the equipment is working. It can take that long for the heater to bring the water to the proper temperature because you may have to fiddle a bit to get the right temperature. Once this is done, it's as safe as it's ever going to be if you are using the fish to start cycling. If you are, only add 2 fish. Test the water daily or so until the ammonia and nitrite levels go down and you start to see nitrate go up. Then your tank is cycled and you can add a few more fish (then you must wait for the tank to do a small recycling for each new fish you add).

Answer 2

Until it's cycled, unless you are doing the cycle with the fish in there and are risking their life, then you only have to wait until the temp is right for them. There is no set time for how long it takes for a tank to cycle, but it is usually somewhere around 6 weeks.

The tank won't cycle or get any sort of good bacteria going unless ammonia is being added by either fish or pure ammonia like you would use during a fishless cycle. So letting it sit for 5 days, 7 days, 9 months it doesn't matter unless there is something for the beneficial bacteria to eat.

Answer 3

Well, you need to put some hardy fish in there to begin the cycle, or buy some starter bacteria stuff if you don't want to use or stress out the fish. It takes about a month after the ammonia kicks in for a tank to fully cycle.

this is a really good link explaining the whole deal. Is it a salt or freshwater tank?

either way, it still takes about a month.

Answer 4

It's not so much about time, but the preparation of the water.
If the water is not properly prepared, it doesn't matter how long you wait, your fish are not going to survive.
Tropical fish require a steady water temperature of 76º to 78ºF. Fluctuating water temperature stresses fish, making them more vulnerable to disease. High quality aquarium heaters minimize water temperature fluctuations.
Electrolytes are essential for the uptake of oxygen and release of carbon dioxide and ammonia through the gills. Without the proper amount of electrolytes fish cannot properly breathe making them more vulnerable to disease. Adding aquarium salt supplies these important electrolytes fish need to help them breathe easier and remain active.
Add only a few fish at first. It takes time for the aquarium to develop the natural balance required to handle a full tank of fish.
The new fish will be stressed from netting and bagging. The best method to add new fish is to float the unopened bag of fish in the filled aquarium for 10 minutes to allow the fish to adjust to the water temperature. Then, open the bag and gently release the fish into the aquarium. The bag water may contain fish waste (ammonia), so try to avoid adding the bag water to the aquarium. Whenever fish are netted and handled their protective slime coat is rubbed off. When adding fish to any aquarium, be sure to add additional water conditioner to help relieve stress

Answer 5

I use to paintings at a puppy retailer and we advised ppl to attend 2 weeks after they could purchase a tank. However, I've positioned them in my possess tanks just like the day after and the fish had been first-class.

Answer 6

Nunya is the only one to have given you correct information!! Ignore the others thye dont know what they are talking about.
A good link is the one below, its a fish forum and the people there know a lot (Im a member there too but I dont know as much as some!!! lol). The second link is to the forum's fishless cycling page.
You can ask any question there and get an accurate answer. Hope to see you there soon ...:D

Answer 7

5 days

Answer 8

you can just put fish in the tank but make sure the tank has plants if it is a freshwater tank and make sure you have water conditioner that removes chlorine and other junk in the water that is harmful to fish. i use Neutral Regulator where you can buy in pet stores like petco or maybe petsmart

Answer 9

Hmm, it's been awhile, but I think it's seven days.

The longer it sits before you put fish in there, the more of a chance it has to develop a sort of natural bio-environment with lots of good bacteria in there to overbalance the bad bacteria.

Answer 10

I would not put the fish in the tank until about a good 24hours.Gust leave the fish in there bags.ON top of there new water so they can get use to it.If you put them in wright away they might die.It give them a stokes.
