New 100 Gallon Set Up

I previously had a 20 gallon tank. I finally decided to upgrade so I got a 100 gallon tank. I bought a new filter rated for 125 gallon tank (canister filter), a new LED light, and new gravel. I set it all up and made sure to wash the filter medium and new gravel. I then filled the tank with new water and declorinated it using a tap water conditioner as i was adding the buckets. I then took my old 20 gallon and pulled out about 15 gallons out of that tank and moved it to the new one as well as the 8 fish that I had in there. I had 3 tetras, a barb, 2 plecos a cory catfish and a upside down catfish. Took me about 8 hours to set up. Now its the next day and when i woke up in the morning my barb and 3 tetras were all dead. My bottom feeders all seem fine. The tank is also really cloudy. Im guessing a bacterial bloom. I also did out my old filters medium from the 20 gallon tank into the new one as to help the tank cycle quicker. As I said, the tank is really cloudy. Its at a out 75 degrees atm and im thinking about picking up a few cheap fish to help the tank cycle. Any ideas on why the 3 fish died? I just did a test on pH, Nitrite and Nitrate and all are 0ppm. I think there may have been a fluctuation in temperature between my big tank and small tank, but of that I am not sure. I also have only one air pump with two hoses. Should I increase to a few more to help with aeration? Any tips on such a big tank? Any ideas on the cloudiness or fish death? Any help and tips are appreciated. Thanks!

I wouldn't add any more fish just yet. You need to figure out what happened first. You said your ph was 0, I've never seen water with a ph of 0, I would retest the ph, make sure you use a liquid test kit like the API master kit. The test strips they sell aren't very accurate. I wouldn't think you have a bacterial bloom, if you just added the stuff from your old tank, assuming it was healthy. If the temperature of the 2 tanks were too far apart when you moved the fish that may have caused them to die. It's always best to cycle a new tank before adding fish to it. Ya, I know it's hard to sit and wait a month for a tank to cycle, but it's better than trying to chase down problems that occur when we try to rush things. Good luck, hope this helps
