In my opinion you definetely need to reduce feeding a lot. And I am a heavy feeder. Less amount per feeding and longer time between feeding. Fish that do not come to the surface when you enter the room is definetely overfed.
Yeah big tips here, your fish can easily go in-between days of feeding when theyre healthy especially. Also with those big goldies in there you should drop a gravel substrate about 3 inches deep with some sand sprinkled in and some easy plants then throw in some pond snails or bladder snails as they will feed the goldfish when their eggs hatch continuously. Your bubbler might be a bit powerful too, im sure youre adding water every few days so i would get an aquarium hood with lights.
