As my other thread stated, I'll be purchasing a 40-50 gallon cube. I'll have to get a new LED fixture. I need some help with direction. I want a fixture that sits on top of the tank, no hanging types. Also full spectrum. I have an Aquatic Life now that is whites, blues, and purples. I love the color output and want to find something similar. Totally clueless as to what's out there since I've always stuck with T5's I can't afford to break the bank either, gotta be affordable. Thoughts? Feel free to post a link if you've got one. Thanks!
