jaddc February 12, 2013 Share February 12, 2013 I would take the lid off first. The hinges have 4 plastic screws holding it in place. I believe (its been a while) that you can access them with the lid closed. Once it is off, you can undue the clear plastic lens cover which has a ton of screws.

jaddc February 12, 2013 Share February 12, 2013 There may salt creep in there, so it may not come off easily. Link to comment Share on other sites More sharing options...

Need to be careful during break-in. A new lamp puts out more light most of the time. Shorten your light cycle (photo-period) by 2-3 hours or screen the top to cut down on the amount of light in the tank, then gradually increase (or remove the screen) over a couple of weeks.
