Did you cycle with fish?

+1 to Dr. Tim's. I went the Dr Tim's + Ammonia dosing route when I set up my QT's recently. Works like a champ as long as you follow the instructions. Welcome to R2R!

Also remember, just because your tank is cycled, does not mean dump in 15 fish at once. Go slow. As I was building up my fish stock I would add a fish every two or three weeks. Never lost a newly added fish.

Definitely agree with this. I added fish one to start, then a pair about a month and a half later after they were QT'ed. Since then, one at a time, with at least a few weeks in between.
