Those are great choices but consider throwing in a purple plus to enhance red and pink corals!

I run the above...with the purple and 3 blue +.

Here is what ATI recommends.

oh, and I highly recommend a 6 over 4 bulb set. It is far more versatile. with a 6 bulb ati light over a 75, you can grow anything you want. And if you find it to be too much light, you can add purples and actinic which reduce par but add pop (or just run 4 bulbs). While I suppose you can get away with a 4 bulb set in a 75, I doubt it would be a good fit for a 90. As I recall, 90s are a few inches deeper and a 4 bulb set just will not cover. Frankly, over a 90 you may opt for the 8 bulb configurations.
