I have got a 8 bulb SFILIGOI on my 90g with the following bulbs and I agree with RDNanoGuy the choice of bulbs is a personal one, I am going with all Giessmann, this combination gives me a more bluish spectrum. The 2 outside Actinic + are only on for about an hour each day, in retrospect I think a 6 bulb fixture would be adequate enough for our size of tank.
