I agree on the filter. Its way to early for a filter like that. The best thing to do is use an airstone and do water changes every day like flumpit2 said. You can add a sponge filter at about 3-4 weeks old. Having the gravel might be a problem since it will be harder to keep clean. Im guessing the tank you are using is cycled? If so, that will help a lot. Mine was not cycled when I started, which is another reason for the daily water changes. The clean water will help the fry grow a lot quicker.
As for the microworm culture, you can get them off Aquabid too. I bought one that was a kit. It came with the oatmeal, culture, container to keep them in, popsickle sticks to get them out of the container, and an eye dropper thing to put them in the tank. It was like $10 shipped. Adding some yeast to the culture will help them grow faster too. You definately need to do something fast, as it will take the culture a week or 2 to get started. The fry will need something other then the Liquid fry after 2 days. Some people have used baby brine shrimp with success. I know once I started mine on the mircoworms, they took off.
Keep us updated. Good Luck
