I had some green dot stuff in my log tank with lower 6500k flouresent tubes also. I have not tried very many 10,000k lights.I have found that, in my tanks so far, the brown diatom algae and the green spot algae are frowing well with the 6500K LED's.
The river tanks I have see a lot more string / filament trype algae growing with the 13000K LED's.
These lasted for 2 years, on a air cooled aluminum heat sink. I used them on both tanks, and had Blue Green algea issues if left on too long, 50 watt 110 volt cobs, full spectrum. They grow potted plants nicely.
