im gona be setting up my 180 soon, and im gona stock it wit a pbass. im realy thinking about using sand, but my concerns r that the colors of the pbass would get washed out and that it would move the sand around too much. what do u guys use? any one using sand? and if not were do u get nice gravel for cheap from? im not trying to spend close to $100 on gravel from a lfs if it comes down to that
