i will be getting some fish i need my 75 gallon cycled pronto.i have a plce to put them but i dont want them in that tank to long.so what chem can i use that will really speed up the process i have heard there are some one day stuff that really work called BIO something.
 
It's called Cycle, it works but I dono how good it works, try getting some gravel from an established tank - this helps alot, Zebra Danios, are good fish to cycle with, there hardy, and will take any thing you put them threw, there also cool fish.

The product it called BioSpira, and it's manufactured by Marineland. The jury is still out on whether it actually works, but some reports have been promising.

In any case, some things that have been around for a while and don't seem to work are Cycle, Fritzyme, Stresszyme.

You can also try getting some filter media or squeezings from a filter on a cycled tank. Gravel from a cycled tank would help, too.

The more bacteria you can import, the less likely you are to have fish loss when you stock a new tank.

try using gravel, decor and a filters off of an established tank. Also you could add some of the water from your existing tank to the new one as well. in my amiricle wet/dry i keep 2 emperor 400 cartridges on the bottom to hold some bateria and when i need to jump start a tank ill drop them into it to spread the goods. seems to work fo rme ive been doing it for a while.
 
There is no proof that Bio-Spira fully cycles your tank. At best, it processes ammonia, but doesn't actually establish a bacteria bed capable of dealing with a heavy bio-load. There are no products out there that are documented as effective. Until they gaurantee their product with a full replacement policy, I consider it bunk. Heck--the Bio-Spira people won't even provide samples to stores so they can test it out...Confidence inspiring, don't you think?

If you can't cycle the tank (even fishless with a heavy seeding would take 10-14 days), then you're stuck doing daily testing and water changes to control the toxins. Understand that your other tank will be cycling as well unless you are removing the fish currently in there completely. Anytime there is a significant change in the amount of waste produced, the bacteria populations change. When the bio-load increase, the bacteria lag a bit behind, and ammonia/nitrites build up.
 
just switch the filters on the new and old tanks. that will cycle the new tank while the bacteria in the gravel of the old will keep that ok while some gets into the new filters. then switch em again. It works great when I set up tanks.
 
JP457 has the simplest answer.

Furthermore, I'd siphon off the surface of the gravel of a mature tank, not digging around with a vacuum, let the detritus settle overnight , pour off most of the clear water and pour that dirt right into the new tank. Let it blow everywhere in the new tank.
 
Good seeding combined with many live plants = tank ready to recive fish.

I no longer cycle new tanks. I use some gravel, decor and media from established tanks. The new tank is planted well with live plants. I then dose 3-4 drops pure ammonia/10 gals water. In 90 mins or so I test. Every time ammonia = 0. I add fish the next day. I have stocked tanks Fully in as little as 4 hours after setup doing this. I have not lost a fish as a result or using this method.
