Well, it's been a little over a month now and I haven't seen any difference in the bulbs in terms of it's "blueness". You can see my original post back on page 15. Neither one of my bulbs, 14k and 10k has gotten any bluer. I still seem to be having problems with cyano after quite a few water changes and can't seem to not wonder if the spectrum of these bulbs could be contributing.:worried: In fact now, it's coming on like gangbusters and it seems I'm doing a large vacuuming almost every week. Since I'm in the middle of this cyano battle, I may just have to go back to the Phoenix 14k just to try and find out. It still remains though that these Plusrites just may not get blue enough for even for me. I like having actinics for the easy daytime progression of lights coming on but dont want to HAVE to use them just to get color in my tank.
