Fish dying.

This is really distressing! Tank is 1 month old. Put in 2 Perc Clowns to start the cycle and monitored it, water was always consistent at Nitrite 0.05; Ammonia 0.25; Nitrate 10.This held steady for 3 weeks so we added an Auriga Butterflyfish (about 2") and 2 days later the Nitrite climbed to 0.2.

We did a partial water change as the fish were showing signs of stess, this brought the Nitrite down to 0.05. The next morning it was back up to 0.1 so we did another partial water change (20% again) Nitrite back to 0.05.

The next morning the Butterfly and 1 of the clowns were dead, they showed no sign of stress the night before. Nitrite still at 0.05 and other readings the same as always.

We gave this a few days and monitored water, no change so we bought 2 black Cardinal fish to continue with cycling the tank. This morning, 2 days later, they are both dead and the only change is Nitrite back up to 0.1. Nitrate still 10 and Ammonia still 0.25.

We have been using a product called Cycle. I did not think a Nitrite level of 0.1 was enough to kill fish and we still have 1 of the original Clowns who is doing well.

What happened? What can you recommend?

Thanks!

The most needed and least added element to any marine aquarium is patients and its free but for you issue at hand . Old Hoss you rushed it
Simply said you rushed let it be and allow what will live to live and get the dead stuff out and wait for 10 more weeks ..
I see many get away with a fast rush cycle set up well they get by with it and then for every few that get by there is as many like yourself that just have nothing but problems ..

Thanks for the input - I wondered if I was rushing it but I was taking all my advice from the LFS. I am learning!

Another question please - now that this has happened I am considering a larger, 75 gallon, tank and put in a Refugium then take it extremely slow - thoughts???

Thanks a bunch!
