what lights to get for my t5

[reefsurfer1]

I have two 48" t5 light fixtures. The hold two bulbs each. Right now I have a power glo and an acintic bulb in each fixture. Its time to change one fixture and I was wondering if that was the best combination or not. My tank is 24 inches high and the light doesn't reach the bottom. I also haven't cleaned the reflectors in 9 months and want to know the best way the get the salt build up off.
Thanks guys!

Bulb selection is tough to recommend as a lot if depends on personal preference. My 4 bulb fixture had two actinics and two 10k whites. I thought the colors were bland. I switched to ATI bulbs ( two aquablue specials and two blue+) and thought it looked much better but still wasn't satisfied with the overall look. I ended up getting a 6 bulb fixture( plus two LED tubes) so I didn't go any further on the quest for a perfect 4 bulb combo.
the reflectors should be cleaned with plain water.
