Here's what that filter that Jess suggested

This is another one I was using, but I don't like the intake for it.

Just grab some filter floss wrap it around the intake tube.
If you don't have filter floss, just grab some plain white cotton balls and pull them apart slightly. 4-6 should be more than enough for the time being to buy you time to find a more permanent solution.
The TopFin WORKS, but I like filters with FEATURES. That TopFin 10 is one of the bottom level filters for beginners because they come with the starter tank kits.
Search around the net or this forum. There's 10000's of people who own this filter & you're not the first person to encounter this problem.
Also, if you've ever been to preschool/elementary school I'm sure you remember arts & crafts. It will require those skills to fix it.
Good luck.
