I just bought a new filter and it has the new "bio-fiber" stuff on it. When I read the package for it, it said that it removes dissolved waste and nitrite. But don't fish need nitrite to grow? I want my fish to grow. I have 4 aquariums each with only common goldfish, 2 10-gallons, 2 20-gallons. 10 gallons with 2 and 20 with 3 fish. I want my fish to grow, but I also want an efficient filter. What can I do?

No, nitrites are toxic and will kill your fish. Anything above 0 nitrites is dangerous. They are a natural part of a fish lifecycle, but bacteria exist that neutralize these nitrites into less toxic nitrates (which you remove when you do your weekly water changes). Basically what the bio-fiber does, it gives a good place for these bacteria to grow. In a normal filter they would just grow on the filter sponge - as well as in the aquarium gravel.
However, your fish will not grow due to the fact that their tanks are very undersized. Common goldfish can easily hit 12 or more inches in length, and they are pond fish, not aquarium fish. They need like 50 gallons of water, each. If kept in small tanks, they will be stunted and will not live very long at all (think about it - these fish can grow longer than the tanks are!)
The filter itself is fine, but you should really get some different fish if you want them to thrive, and bring the common goldies to a goldfish pond or back to the LFS.
