I'm an experienced freshwater aquarist, but I'm not so strong with saltwater. I have a little experience with the maintenance of saltwater.

I'm planning on setting up a 20g saltwater tank for my girlfriend as a christmas present, of course she wants to start with a nemo tank. So I'm thinking maybe a clownfish or two.

I was just curious as to a recommendation for a filter. I don't want to make this a reef tank because she is a beginer and I'm only going to be able to help her so much with maintenance, and I also don't want to spend huge amounts of money on lighting. I just have a standard 15 or 20 watt light, whatever the versa hoods come with these days.

Then as far a substrate, I believe something like crushed shells or sand is helpful to keep the water in a stable level.

Any other help or recommendations would be helpful, thanks!

It's not that hard.
