diy led project

[Chris86]

I have a 36 gallon bow front tank with a center brace so I want to make two led lights to get around the shadow from one light. Rapidled has a 6x10 heatsink which would be great for getting around the brace. My question is I donno how much light I need I was looking at a light with these
1x Odyssea 250W DE HQI Bulb 15000K
4x Odyssea 24W T5 High Output Bulb Actinic Blue
4x Dual Bluemoon LED
But everyone has talked me out of it so my question is what kinda leds and how many. This will be my first led diy but not first wiring diy i have done.

I have a 30g high and have 120W led over it. I would say 50/50 white/blue with a couple of purples mixed in. 4led moonlight
