I used pool filter sand. play sand seemed too fine and dusty. make sure you rinse the sand first.
don't worry about vacuuming. you don't loose too much sand and it is cheap to replace.
i just switched to sand, and I love it. it looks great, and my aquarium is cleaner than its ever been. with gravel uneaten food and poop falls down into the spaces between the gravel. with sand, there is no uneaten food, because it stays on the surface of the sand to be eaten, and poop is easy to see. you can spot-vacuum. I also use a HOB filter, and find lots of turds stuck to the intake grate every day (which is easy to clean, I just use a net). never had that before. makes me realize how dirty my tank was with gravel.
I didn't rinse my sand (impatient) and it was cloudy for about 3 hours.
I took my fish out, removed the gravel (left a little bit, for BB purposes), added the sand, and once it started to settle a little (about 1 hour) added the fish. cloudy water doesnt really hurt the fish, they dig through the sand, anyway. by the next day they seemed happier than ever.
pros- 50lbs of pool filter sand was less than $5, and more than enough to cover a 55 gallon. easily enough for a 75/90. other dude said his fish moved the sand around too much. I'm having the opposite. my fish moved gravel too much. they don't move the sand as much.
