That one will work. I know people will say they don't like the look of a 6500k bulb, but I happen to find it much more pleasing in a mix over the Coral+ or the aquablue special. Both those bulbs have an off-putting green look to them, whereas the 6500k has a warmer almost redder look. Up until this year I ran an 8 bulb array with 3 of them being 6500k bulbs and I even wanted to throw one more in there. Theyre great bulbs that put out a lot of par and in my experience help to develop color wonderfully. Theyre cheap enough that you can try one and if you hate it, its not that big a deal
