As mentioned before, you threw out all the BB which was helping to keep the tank clear and helping process the fish waste.
It should require 75% water changes maybe, even 2x per day to keep that water clean.
You need to get a test kit to measure all your Ammonia, Nitrites, and Nitrates, this is a serious situation for the health of your fish.
PLEASE get the fish into a new tank or rehome, the suggested minimum size for a Goldfish is 20G for the first fish and 10G for each additional fish, and a turnover rate for your filter of a minimum of 10 x your gallons per hour /50 Gallon tank 500 gallons per hour.
Also can depend on your feeding - food type and quantity.
And how often/much you do pwc
