I like Joe's method.
The other Joe from years ago had another great idea. Use a small pump that was plumbed with a hose to a water filter that had a 1 micron filter in it.
Another method that I use for my saltwater tanks is to take a seven inch filter sock and cut a hole for it in a bucket lid. Then put the lid and sock on a five gallon bucket and then syphon as usual. When you are done, remove the lid and sock and pour the water back in the tank.
