I purchased an AquaMedic Ocean light 150w HQI halide ballast for the AquaMedic Ocean light fixture I came across. Problem is the "new" ballast doesnt work. Whenever i plug it in it trips the GFI, on 3 different circuits. So i know it isnt my circuits but the ballast. Anyone familiar with halide ballasts to tell me what I should look for to get it working? I thought perhaps becasue it was so cold when it was shipped that condensation spread through it once it got into the heated/humid aquarium room. But i have let it sit for a week and it still does the same thing. Inside everything looks good clean and tidy. Any suggestions?
