Start by doing some big water changes. I'd do 60-70% now, leave it a couple of hours and then repeat.

Have you got a test kit that will check for ammonia and nitrites?

+1; big water changes with warm, dechlorinated water is the best emergency measure you can take with fish.

Those weekend blocks are infamous for rotting down and polluting the water. You can go away for up to two weeks easily and not worry about feeding the fish.

Hmm that's terrible. Sorry to hear that. The guys have offered the best recommendation with the water changes! I now know not to ever use these foods.
