Sponge filter cycling

I have a small Discus hatchery with 3 20 gallon tanks with breeding pairs, one 75 gallon tank, 2 60 gallon tanks, and two 30 gallon tanks. I use the "Rainbow" brand double sponge filters (each sponge is about 6 inches x 2 inches. My large tanks have two filters (4 sponges) in them and the small tanks have one (2 sponges). I moved to a new home almost two months ago and I tried to preserve the biological cycling on the aged sponge filters by packing them in 5 gallons cans with aquarium water. When I setup my tanks in the new location I discovered 4+PPM of ammonia in all my tanks. It seems all my sponges had un cycled. I had to use a triple dose of Amquel daily to remove the Ammonia and all the fish became very lethargic. I recognized that they were under extreme stress.
