So since switching over from my 150W MH 14k Phoenix to my DIY Bridgelux LEDs (Aquastyle Online) I have had a weird algae bloom. Im am running about 24 LED's currently (9 white, 16 blue) at full. I have definately noticed my amounts of green hair algae have bloomed very much in addition to a weird brownish tan algae on my sand. Just fyi, I am not using RODI and i know i should. I will pickup some from my LFS soon but since im having surgery tomorrow it will have to wait a bit and continue with tap for now. Regardless of the RODI, the leds have definately bloomed these algaes more. Any thoughts on the brown? Cant be diatoms, and doesnt look like dinos... sorry bout the color, but the iphone cant pickup the color of the tank while LED's r on. You can see the clumped sand though.
