wash sand in bucket until water runs clear, turn off filter, scoop out gravel with dustpan, scoop in sand, let settle for 10 mins, turn on filter.
If your gravel is really messy, you might want to drain off some water from the bottom and attempt to suck up some crap before the sand goes in.
see my log for a rough idea on how long it takes for cloudy water to dissipate
Consider cleaning filter out after a week using tank water.
No, you dont have to remove the fish (but its your choice, depends which you feel will be more stressful, catching them and putting them in a bucket for 30 mins or just leaving them to it)
Job done.
I just changed my gravel for sand. I did it exactly how tizer discribed, leaving the fish in. Except I took the gravel out using a dustpan and then waited til the next day to add the sand as the water went really merky. All went well, all fish are fine and looks so much better. My corys and plecs are lovin the sand.

Alot of people use play sand but from what iv read, no matter how many times you wash it, your water will cloud badly for upto 2 days.Are there any types of sand that should be avoided? I happened to see a bag of sand from a local Home Depot, and the bag said "Not to be used in aquariums".
I've heard play sand is a good (cheap) choice, with plenty of rinsing, but this bag of play sand makes me wonder about why they would say that...
