absolutely, in fact you should definitely eliminate the canister filter. A good supply of liverock (1.5 to 2 lb/gal), good flow in the tank (from your powerheads and proper rock arrangement), and a quality skimmer should be the foundation of your filtration. Optional things to add for filtration include carbon reactor, phosphate reactor, UV filter, and deep sand bed. The carbon and phosphate reactors are similar to canister filters, built for holding activated carbon or phosphate absorbing material. A UV filter helps kill free-floating parasites and bacteria (depending on the flow rate through the UV unit), helping to fight the spread of disease in the tank.

And as far as the sand bed goes, definitely don't use crushed coral, use a sand substrate, aragonite sand is a great choice. Most importantly, choose the depth of your sand bed carefully: either use 0.5 inch or less, or 4-6 inches. Don't go in-between, the 0.5-4 inch range is deep enough to trap waste and allow it to pollute the water, but isn't deep enough to grow anaerobic bacteria which will help keep your nitrates at zero. If you want sand but not a deep sand bed (just for looks sake), then go with 0.5" or less that way it isn't deep enough to really trap wastes. Otherwise, use 4 or 5 inches of sand, and in time certain bacteria will grow in the deepest parts of the sand bed where oxygen can't reach, and it will consume nitrates and convert it into harmless nitrogen gas. If you choose to go with a deep sand bed, then be sure that you don't disturb the sand bed when you clean your tank... no need to vacuum the gravel. You can keep things such as nassarius snails, sand sifting starfish, and other sand stirring creatures to help keep the sand bed stirred up naturally and the upper layers clean of detritus and other wastes. Nassarius snails are really cool by the way

Okay, sweet, I never realized what a problem that freaking canister would be in my room which is all carpet, not to mention ive never used one, im def. gona grab a good skimmer and power head and try and get rid of the filter. how much could i get for it? Also, I thought 1 inch sand bed was good, I bought enough sand for a 1 inch bed, including live sand to mix in.

This is very true.

I would suggest the DSB (deep sand bed). I think that you will have fun with the animals that you can keep in the DSB, like the Sandsifting Starfish and the Nassarius Snails. Maybe a Diamond Goby (I bought it named a Polaris Goby) they tend to burrow and sift through the top layer of sand. They are fun to watch.

If you do go with less than 4", like conger said, use less than 1".

It's a pain adding sand down the road. It's best to make sure that you are as set up as you want to be before you add your first fish. After that, you don't really want to disturb the enviroment all that much.

I think (though I haven't done this) that you can use regular sand. The Live Sand that is already in your tank will seed the dead sand with beneficial bacteria. But you have to make sure it is Silica Free. I don't know if play sand that you buy at your local hardware store is silica free or not.

I'lll check at work and let you know.

The way to add the sand is to get the sand bag and put it into the tank. then while it's down there open a slit into it on the under or side and allow water to soak it. Then increase the size of the hole and slowly release into the water. That'll keep most of the sand from blowing around as much as it could be. Also, turn your pumps off when you release and non-livesand will be more free floating then live sand so keep that in mind when you add.
