New Light System

[demosthenes]

I just won this new lighting system from ----. I'm so happy. I'm not sure if I should use 10K or 20K. Any suggestions?400W MH Pendant

I have one 10K bulb and one 20K bulb. The 20K bulb is much bluer. It also makes the rocks look greener. I'm still undecided on which one I prefer.

I have used the 12000K bulbs since they first came out. I have heard a lot of bad thing about them, but have never had a problem. I think it gives a good balance in between 10000K and 20000K. Little more blue than the 1000K, but bright enough to really shimmer in the water. It also makes the fish and corals flouresce nicely.
