That's true. You should by a small gravel vacuum. It will cost under $10 and it will help you big time with the cleaning. They make it easy to get the filth off the gravel bed where it hides. I have a big one for my big tanks and I think it was under $15. All a gravel vacuum is a powerless siphon. I even use one in my bettas 5 gallon tank.
