This is what I would do.
1. Disconnect the airline from the pump tie a knot in the line to control the amount of drip into the bucket, and put one end into the tank the other into the bucket after starting the syphon.
2. Do a large water change on the tank.
3. After about 1-2 hours of drip acclimation, replace fish into the tank (watch closely for fish gasping at the top of the water) if fish swim around normally, just watch parameters, if they gasp at top - another water change.
4. Do water changes to remove cloudiness and as fish require (see #3).
