I have had a reef tank for 5 years and was never able to get my nitrate to 0 until I built a algee truff scrubber, cost about $35 to build and takes about 4 weeks to get to 0 but now I test 0 all the time and ph is never a problem either.
look great, where did you buy you led bulb at? I just bought a led fixture from ledwholesaler 71 white and 41 blue but might need some spots, for full coverage, what PAR are they ?
