Thanks for the email! That tank will need about 120 LEDs with 40 degree lenses, so the 180 kit won't quite be enough. However, you can go with that kit and add on another heat sink, more drivers and an additional driver as needed.
Here's the rule of thumb as far as colors go: A ratio of 1 Cool White to 1 Royal Blue will give you a 13-14k color temperature, a ratio of 2 Royal Blue to 1 Cool White will give approximately a 20k color temperature, and a ratio of 2 cool white to 3 royal blue will be 16-17k.
For 120 LEDs I'd go with something like:
4 red
4 green
16 UV
60 Royal Blue
36 Cool White
You can add a controller later, in the meantime get the 2 color dimming kit or at least a 10V adapter (without any voltage the lights won't ever come on):
