I try to do 30-40% every 4-5 days along with a gravel vac. I've got sand in my 80g and 40g tanks, but I'm think about using tiles in the big tank I'm planning as I hate the way a bare-bottomed tank looks.
I drain the tanks to the height of the biggest dat with a Mag 9 connected to a garden hose, I then have another hose connected to the outside faucet connected to a pvc hook that hangs on the tank. I cycle the water for about 10 minutes then fill back up. About the tiles, sounds pretty cool. I was thinking about using retangular cut slate to either line the bottom or silicone to the back of the tank. I'm sure it would look really nice but I'm sure the dats wouldnt care for it. They prefer soft water.
