This is the "Upgrade kit for the 24g nano cube, that I bought at Aquatek in the back. Well I changed my mined and I no longer need this hood. The 150w MH works fine I have pics at request, the only downside is that they guy that left it at Aquatek took off the the LED ballast! I think you can get one of these at Radioshack, and if you'd rather have me fix it I can, but I'd charge whatever fixing it cost (ill save recipt). Im asking 150$ OBO.
