Keith -
Not sure how often you check this forum, and I will certainly call tomorrow, but i was planning on working on my fixture today when I realized that unlike my previous problem last November, I have 4 lamps not working (the 4 on the inside).
Does this mean I need 2 ballasts? What should I do to trouble shoot? If it is the ballast, does ATI still sell ballasts for my generation of Powermodules?
Thanks.
Joe
P.S. For everyone else I have been running the fixture with only the 4 outer lamps for about 9 months and my corals still look fabulous not to mention the bulbs are almost 2 years old now (yes - I tried new lamps in the slots that are not working) so long story short 99% of the time the fixtures we have provide more than adequate light.
