I bought a 10000k flashlight for my 5 gallon pico reef. At high power I only need some actinic light to fill part of the spectrum needed by the corals. The main reason I went with 10000k was to get enough intensity to grow coral as I said I would still need some blue to get the full spectrum I wanted but I would have no Windex stained water.Super fast delivery from Revain!
