Frankie is in the hospital again, this time for a while. His son told me the ballasts has gone bad on his metal halide light and he cannot find another dual ballasts as the company that originally made the light is out of business. He was thinking about upgrading the lights to LED, yet we need a little help with this as it is a big tank and Frankie has some mature coral in the tank 150-175 gallon tank. Can you please call me at 914-319-3381 to discuss the best method. Thank you very much. Veronica
