Opinion about lighting

[frank88]

I have a tank 190cmx80cmx80cm with DSB 15cm...

now i have 3x250 watt metal halide 14.000 kalvin + 2 T8 58 watt 21.000 kalvin

my project is 3x400 watt metal halide 20.000 kalvin + 4 or 6 t5 80 watt...kalvin????


what you tink? 20.000 kalvin metale halide is my big doubt, but i worship blue and its effects...such as neon flank

sorry for bad's english, thanks!!

74"x32"x32" with a 6" sand bed. If you like the blue, then by all means go with the 400 watt 20K. Can we assume that it will be a sps coral tank since you are using such intense light?

Why not try 20K in your 250 watt fixtures?
