A lot of people here, myself included have found much better growth with large daily water changes. As Willie said, you still get slime forming on the glass and sponges and need to clean them so there's still plenty of food for the bacteria to live off.
Mine usually get a FDBW treat straight after the water change so they usually get excited at water change time knowing what's coming next lol.
