Hello everyone, Im thinking about upgrading my lighting. I want to move to metal halides. I have a 29 gal tank. the length of my tank is 30". There arent too many fixtures available. I was thinking about getting a pendant fixture and hang it over my tank, plus I really like the way that they look. My question is...will one pendant light be sufficient, or will I have to use some sort of retrofit kit and make a custom fixture? Also, I want to be able to keep just about anything in my tank. How many watts should I be looking at? I currently have about 130w, and I really do not feel that its enough. Any input would be greatly appreciated.
