Can I put goldfish in tank after just a few hours of filtering?

My son won two goldfish at carnival. I bought a bowl to house them until I had chance to set up tank. Used the water from their bag and spring water.

I syphoned out a lot of dirty water and added some spring water. Surviving fish seems to be swimming to top a lot for air. I know I'm supposed to introduce them to new water gradually, but I'm afraid if I don't put in tank now, he won't make it through the night in the bowl. Any thoughts, please?
