My cousin who has a tank and knows alot about aquariums works at the store im talking about. He is showin me the kind of stuff to get. Hes not trying to make sales he just trying to get me good equipment. Ill have to check about the canopy. Im not getting metal halides due to the price. Im getting PC florecent which i was told can grow some types of reefs. I got the book Saltwater Aquariums for Dummies which seems to be a good guide. Ill have to check into those other books also.
