Hi everyone. I've been lurking for a bit and I am very excited to start a waterfall ATS for my 330 gallon. It is nicely stock with various tangs and 2 angels. I feed heavily - everyone is fat and happy! With that said, I am going with a DIY 10 cube setup. The dimensions will be 15" X 8". Even though I have been reading a bunch I am still unsure about a few things and would appreciate your advice. - First need your opinion on lighting. I am going with DIY LEDs since I have drivers, power supply and heat sink that I got from Steve's LEDs for a previous pico tank that never took place. I have ordered the LEDs and going with 8 X 3 watt 660 red and 1 X 3 watt royal blue on each side in a linear fashion: red | red | red | red | blue | red | red | red | red The heatsink i have is 3" X 15" X 1.8" fins for each side. Think this would work? - Second, can you guys confirm that there will be no difference between a 15"X8" VS. 8"X15" configuration? Thanks in advance for your replies and suggestions.
