Which filter for a betta tank? and what is the purpose of gravel?

I am planning on getting 1 Male betta fish in a 10 gallon tank alone, and which of these 2 filters works efficiently and does not have a strong current.

Should I replace the filter cartridges monthly or every 2 months?

**Internal Filter**
http://www.petsmart.com/product/index.jsp?productId=2753028& lmdn=Fish+Filtration+%26amp%3B+Circulation

OR

**Power Filter**

http://www.petsmart.com/product/index.jsp?productId=2752295&lmdn=Fish+Filtration+%26amp%3B+Circulation

( it says that this one has an adjustable flow rate, I dont know if the 1st one has that )

And what is the purpose of gravel? Does it assist in biological filteration?

You want a filter that isn't too powerful, the best are air-pump-powered sponge filters or internals with a spray bar that cn be positioned towards the back of the tank. (Your links aren't working for me.)

If by filter cartridge you mean the sponge insert - you don't, not until it's falling apart. Over time, the muck that covers the sponge breeds the bacteria that comprises most of the biological filtration. By throwing it away, you undo all that. All you need to do is rinse it out in a bit of old tank water (*Not* tap water, very important.) to get the worst of the gunge off. Even when the sponge gets so old that it needs replacing, you should never replace more than 50% at a time and don't replace the rest for a couple of months. Don't be fooled by the money-grabbing shops!

Good bacteria does also build up in gravel, but mostly it's for looks.
