I would just go with the fishless cycle. This way your not exposing any fish to the harm of the toxins in the water while doing the cycle and then you dont have to worry about what to do with the fish afterwards.

Besides of a bottle of ammonia is gonna guarantee your not infecting your tank with anything.

dude just buy a sponge filter and throw it in an already cycled tank let it seed till they come and itll cycle immediatly when you put the spongue and fish in.. that fishless cycle seems like a huge pain and takes just as long as cycling the tank by adding 2 fish every 4 or so days... big waste of time if you ask me.. *** yet to have a problem cycling tanks by seeding cultures in sponges in already established tanks

Gotta differ with you Mike. :)

That'd take weeks and no guarantee that the sponge would harbor enough bacteria to handle the fish load after spending all those week seeding.

that fishless cycle seems like a huge pain and takes just as long as cycling the tank by adding 2 fish every 4 or so days... big waste of time if you ask me..
It does take just as long. The benefits are many, but shortening cycle time isn't one of them. Seeding is the way to shorten cycle time and when you mix it with fishless cycling, you get the best of both worlds. 7-10 days to fully cycle with no spikes or exposure to toxins even when adding a full load of fish right away.

And fishless cycling is very easy to do. You see the posts here of a few that have some problems, but dont' see all the instances of it being done without problems. We're working on a new fishless cycling article for the forum, btw, that hopefully will help.

I've done this myself, but always tested it out by adding ammonia. If seeding was effective, it adds a day or two. If it wasn't, then be glad there's not fish in the tank. It's an extra level of caution that I'd recommend when I'm dealing with someone else's fish. There are just too many variables that can affect the effectiveness of seeding sponge filters.

well i usually add the sponge that was originally in the tank and leave the new one in the already cycled tank.. the bacteria in the filters of the already cycled tanks ensure they wont have a spike.. the sponges are just a good buffer

Maybe yes, maybe no. My point is that you can't always guarantee that will work. If a sponge is gunked up with little or no flow, it may not. Even if clean, no guarantee. I have tested this by moving seasoned sponges and adding some ammonia. Often some days were needed to process that ammonia. It's up to each how cautious we want to be with this.

gotcha... what i usualy do is add nutrafin cycle for a few days when i first setup a tank.. but *** done it a few times where i moved all my fish from a 125 to another 125 with new media in the canister filters and jus moved the 2 big sponges that were in the tank and no fish have died... i always squeeze my sponges out a bit every week during the water change so they arent too gunked up.. but i feel what you are saying something i wanna do that isnt proven 100% effective shouldnt be suggested to others jus in case it does backfire ok.. well all i can say is i have done it and i find it works well... but like prov said if you wanna do that and the fishless cycle or jus test the water or add the bacteria cycle that would increase your chances of it working well

"Dirty water" will not seed your tank. The bacterial colonies don't reside there, they reside on the media, substrate, and decoration/rocks in the tank. If you could get any of that from your LFS, it might help, but the water won't. That is my understanding.

The nitrifying bacteria attaches itself to surfaces, yes, very little in gunky water.

See the article in the forum library on Fishless Cycling.
