My fish are dying Why2007-11-24 23:39:10

About 5 days ago, I took out all the water in my 96 liter since it badley needed it although I know it would have been better to leave like 20% of the water in so I don't take out all of the bacteria a tank needs. Anyway, it was beautifuly clean and i put lots of new plants in. After about 2 hours I put my fish back in (which are all compatible with each other) and from that day on till now, about 10 of them died! Could this have been from the water change? But then after about 4 days after I cleaned it, i bought some new fish of the same species that died, they were doing great and today i woke up to 3 of them dead! this couldn't have been from the water change since this was like 4 days after.right?

Answers:

When you did the massive water change you killed off the old fish by drastically changing the water parameters (which is why huge water changes are a big no-no).

When you thoroughly cleaned the tank, you wiped out a huge portion of beneficial bacteria. Because of that your new fish perished from ammonia poisoning.

1. Never let your tank get to the point that it needs cleaning badly. Routine tank maintenance will prevent this from occuring (weekly water changes and minor cleaning every other week will keep a tank in better shape than one that is thoroughly cleaned every few months).

2. Don't judge the cleaniness of water by it's appearance or clarity. Big mistake to do that. Instead use test kits to determine water quality. A 'dirty' tank with 0ppm ammonia and nitrite is safer and better than crystal clear water with 5ppm ammonia.
