| i don't think that you'll have a problem burning sps in this setup. the stock bulbs jbj uses for these tanks seem pretty blue (to my eye at least). it also kind of depends on what you're looking for; growth or color. growth go with 10K. color 20K, but like I said, I think that the stock bulb is pretty blue. i definitely would agree with phurst ... 20K's are sexy fun!!
curious, how did you burn your sps in that last setup? bulb too close to the water surface? corals too close to the top? |
