On my 55G I have a 54W T5 HO 6500K "full daylight" and two 15W 18" T8 6500K, so 138 total watts of full spectrum. I also have a 54W T5 HO 5500K Roseate.
I will say this - given your total wattage, I'd dump the Roseate. Depth penetration of 5000-5500K lighting is pretty poor, so it will only affect your tallest plants and even then, it's only going to help certain ones. It makes my Ludwigia turn downright pick, for example. But it doesn't even get to my crypts because they're too deep. You'd be better off adding another 28W of 6500K full spectrum light.
Thank you for the advice! Sadly, I'm not running HO. I just have 2 - 48" Coralife Aqualight 56w double strip light fixtures over my tank.
In one of the fixtures I have 1-6500k + 1-10000k. In the other fixture I have 1-6500k + the Roseate. I had considered changing out the Roseate w/ another 6500k, but I was afraid that would produce too many watts per gallon. Btw, I'm not using CO2, just dosing Excel.
