I'm ordering a 2 bulb T5 retro-fit to add to my AI Sol LED fixtures on my 90g. I'm adding because I want to add a bit more light to the tank and I also feel that I'm missing some of the red in my corals. Reds appear more orange when transferring from other tanks to mine. What bulbs would you recommend? Would you use two of the same bulbs or two different bulbs? I was thinking 2 B+ or 1B+/1AB Special but I'm open to recommendations.
