I am not sure why this is so damn complicated. Pat good money for a light and they send you 0 things for mounting it. Like not even screws that fit the holes they made. FFS. Now that my rant is over, could someone tell me what the hell I need to get and where I can find said thing please? Here's what i have. Aquaticlife T5HO 36"L X 24"W fixture. I presently have 2 AI primes mounted in there. I just got an AI Hydra 32 in and I need to add it to the mix. The fixture i have has the 7" gap in the middle for the addition of lights. Where can I get the mounting hardware, what size screws does it take, etc? I greatly appreciate any help or guidance in this matter.
