Hope someone can shed some light on this for me...... sorry that was unnecesary. I have 2 250w 14k BLV's running on a 2m tank about 50cm above the water. i have the the fittings and ballasts in the lighting hood for another 2 mhs. i raised the hood to its current height in preperation for the extra 2 250w mhs. my only concern is that i almost lost a few lps ( false brains, candy cane ) and one or two other colonies when i upgraded from 2 150 ventures to the 250w blvs. there seems to be enough light and everyone is quite happy so the extra lighting is more for asthetics than anything else. would putting 20k blvs (would look awesome) cause less stress ie light shock than say putting another 2 14k blvs.

4 x 150w would be more appropriate.... however... even these on a 500mm deep tank could be to bright. If you are just using for lps i would not waste the juice on 250watts.
As for the higher 250w Kelvin ratings for lps; many will adapt, but will fair better under the type of light that T5'S produce.
