I purchased a piece of driftwood for my 110 gallon tank a few weeks ago. Until recently, the only things in the tank were a synodontis, giant bumblebee catfish, and a musk turtle. A little over a week ago I bought a peacock bass, which died the next day. I was unsure how he died but figured it was the stores fault. Then, about a week ago, I bought a spotted gar. The gar's scales began to peel and his color dulled. I added salt to the tank and bumped the temp to 82. I then bought a polypterus palmas polli and put it in a 20 gallon tank using water from the 110. The gar and the polypterus died today. I am wondering, do you think it's a bacterial infection? Do you think it is caused by the driftwood. Advise is much appreciated. Parameters are fine on the tank.

How long has your tank cycled?
 
I had to write the first post quick so I will give some more info. Tank had been running for about 7 months. I had a bunch of fish in it for a while but decided to change it up. That's when I added the driftwood. The driftwood has green and white mold looking stuff growing on the part that is sticking out of the water. I got it from a friend who said he cured it but idk if I believe him. Also, I got the fish from three different stores. All looked healthy when purchased. The gar had some torn fins when I bought him, the guy at the store said it was from the pacu in the tank with him. But I noticed the polypterus' fins looked a little frayed when he died. Maybe fin rot? There was also two small red areas on the poly when he died. Any ideas?

I plan to take the driftwood out. Should I do anything else to the water to kill anything that may be in it? I was also thinking about maybe putting the synodontis, bumblebee, and turtle in the 20 and completely taking down and cleaning the tank and starting over. I would like to avoid this if possible though.

It doesn't sound bacterial to me.
How often do you do water changes?
Many times if not often enough, the water becomes acidic, and although the fish that started in the tank have slowly become accustomed to it, but if you add a new fish, (especially because you find dead the next day), couldn't take the drastic change.
Treating fish with medication, when you don't really know the cause could make the problem worse.
 
.... in other words, the best medicine is to do some heavy water changes.
test your tank water and your tap water, then compare the two.
