I am looking for a used LED fixture, I need it to be dimmable for both whites and blues separately. It would be awesome if it had reds, greens and UVs as well but that would just be a bonus. PM me with what you have and how much you are asking please. I have some none fish related items I can trade, and will respond to PMs promptly. If you have multiple fixtures I would possibly be interested as well because my father would need two for his tank as well.
