Help!

[carrie1429]

There is something going on with my tank. First my longnose butterfly dies, then both my yellow tail damsels, showing no signs of disease. I do a water test, all levels are fine,(Ph: 8.1, Amm:0 Nitrites: 0 Nitrates:0). I did a water change yesterday and today all three of my percula clowns died, my coral beauty and scooter blenny. All that I have left is my firefish. Does anybody know whats happening to my tank? Any help would be great.
Note: My tank is through cycling.

Give us some more info about your tank. Type, size, what you have in it, filtration, salinity, temp?
Any disease lately? Any external sources of contamination such as cleaning chemicals? Do you use a deadicated bucket to do water changes? Is it possible that your bucket has been contaminated?
How long has the tank been set up? What water are you using?

My tank is an 84 gallon fish only tank with 80 pounds LR with LS. I have two wet/dry filters. I keep my temp. around 78-79 and my salinity at 1.021. I have had ich before in one fish, but I was able to cure it before it spread to any other fish. My tank has ben set up for about 2 months and I am using distilled water. (water has no chlorine). The bucket I use for cleaning is new and I have only used it twice.

Is it possible that the tank has not fully cycled yet? <img src="graemlins//confused.gif" border="0" alt="[confused]" />
