level
 

+ 1 on checking your level.level your level and draw a line.turn your level upside down on the line and see if the bubble is level.another way is use some clear tubing filled with water(water level).also a 4' level is more accurate than a bullet level(size matters http://www.canreef.com/vbulletin/ima...s/icon_lol.gif)
