Reef needs a "POP"

[The_Strobe]

I am not sure what is going on in my 300 gal. mixed reef. Things just don't look great to me as they have in the past and I have no idea why. The tank has been cranking along for 5 years and had really settled in but in the past few months if does not seem to have the same coloration in the corals ot extension in the polyps and softies. The lights are about 1 year old and will be changed this week. All levels are fine CA is a bit high 500, but other than that all is normal. Anyone go through this? Is there something I should do for a tank of this age?

if you say that every thing is in order then keep doing it the same way, the only thing IMO is that for a tank of that magnitud i would recomend to change the lights from 9 to 11 month...
