Fastest Way to Cycle?

Can anyone tell me what the fastest way is to Cycle new water in an established tank? I recently puchased a blue tang & it must have been sick becasue now all of my fish are dying. I would like to just do a 100% water change if possible & No I don't have a quarantine tank.

The 100% water change would do more damage than good. It would upset your whole balance, cause a new cycle in the main tank and most likely would not cure any disease or problem that may be associated with your fish, in fact it may just kill more fish during the ammonia part of a new cycle alone, not to mention stress them making them even more ill.
Honestly the QT is the correct long term answer, that and finding out just why your fish are dying.
What symtems did the fish have? ick, fungus..etc..?

Not sure what is wrong with them, I just found 2 fish dead yesterday. They show no visible signs of illness. they were just found laying dead at the bottom of the tank.

What are your current water paramiter in exact numbers for ammonia, nitrite, nitrate.
You may have exceeded your bio load
You may also have caused alot of stress in that small of a tank by introducing a Tang that should at least be in a tank of 4-5 foot length.
What are the fish that you do have/had?

All my levels were perfect, except for my Nitrates were really high.
pH: 8.2
Ammonia: 0
Nitrite: 0
Nitrate: 60

I would suggest a water change to bring those nitrates down.
Nitrate is the least toxic of the elements of the nitrogen cycle and the effects on fish are normally due to long term exposure.
Some of the effects can be summarized as follows:
Poor growth
Loss of appetite
Lethargy
Chronic stress
Reluctance to breed
Increase in gill rate and gasping
General ill health
Delayed wound healing
Clamped fins
Are you by any chance using crushed coral or Under gravel filter?

I think your right.
I am using crushed Coral. Although I would like to switch to live sand. Would it be adviseable to add live sand at this point? or would I have to do that during a Cycle?

What kind of tank do you have right now? Fish only, is there any live rock, corals..what?
I think you would strongly benifit from removing the crushed coral. I went through that before and had higher readings than yours.
In your case also if you are using carbon than I would change it every 48 hours as I suspect that it is being exhausted within that time frame.

It's a 35 GAL Upright (vertical) Tank.
I have 1 big Live Rock, 1 Clarki Clown, Yellow tailed Damsel, Cleaner Shrimp 4-5 Crabs, Starfish & a few snails.
I have a carbon filter in my overhead filter with a bio wheel that was changeded about 30 days ago

how many fish did you have at your peak. It may be that your bioload was to heavy or the fish where just to crowded and stress took it's toll. Do you use tap water or RO/DI water? If you do keep the C/C then make sure to vacumm it out during water changes to remove gunk that has been trapped.

I had 2 that died so a total of 4, One thing to take note of is that my clarki clown started nipping at my tang, at one point it started dragging it around the tank by its tail fin. It was probably thinking it was food becasue it was a baby ony about 1/2 - 3/4 of an inch long

more LR may help, more place for them to hide, but add them slowly.

(since you have tang, check carefully for ICH too)
