I'm selling my almost new AI Hydra 52 HD's. I have 5 units. 4 of them have been used for less than a month (they were setup on August 14) and the 5th unit, I opened the box, but haven't used it yet. I am going back to MH's because my tank is too tall (32'') and I'm not happy with the par toward the bottom. I'm not knocking them at all, I just feel taller tanks like mine need to stick with MH's and I should have followed that advice before splurging on the LEDs. I'm looking for $525 each for the 4 units I've used and $550 for the one I haven't used. That price includes shipping. Please PM me if interested.
