see i use my airpump 24x7 but i also have c02 injection so it is kinda a have to at night.

If the filter is only a week or so old I wouldn't bother ''cleaning'' it yet. That's probably one of the prime areas where the bacterias you want to break down harmful stuff in your tank will build up. Of course it will have to be cleaned eventually if it becomes clogged, the filter pads don't allow enough water flow-through, or your impeller gets all jammed up with stuff.
Jweb is somewhat right. The bubbler may not exactly help a great deal. If you ever get plants though its a sure bet you won't need it during the day, as plants produce oxygen by day, but consume it at night, which means a bubbler would be crucial at night. :)
For resizing pictures google picasa. Picasa is made by google so not hard to find. It'll find all the pictures you want it to after you install it (small program, free) and you can just load up one of your pics to the editor by double clicking it in the browser, then just export to/for web. When it saves there should be an option to reduce teh size of the photo by reducing the quality a little.

I only use "stress" products that come mixed with dechlorinator and add it when I add water or sometimes when I'm establishing new fish.
