Gold Fish Part 2

Yesterday Morning, I woke up and was trying to get ready for work. I went to check the fish tank before leaving for work. First I realized the water is very cloudy, then I saw one of fish is not moving. Yes, it's dead. After my wife did some research online, and asked around, we determined that the water is the cause. It still had too much chlorine. She went out and bought a water fighter and pump thingy, which suppose to clean the water up and keep it fresh. It's working fine so far. The left over fish is doing fine in the tank with new water. I think it's ok to add couple of smaller gold fish in, so we bought two more today. Hopefully I can finally have a nice aquarium myself.
