Just broke down my tank to do a new 180 build and this light will not fit over it. The light setup is a 36" t5 four bulb with 2 coral plus and 2 ATI special blue. I bought this from a club member not to long ago and it worked awesome over my 40 breeder. Asking 125 and can meet today or tommo. Pm me if interested. Thanks. :thumbup:
