Actinics . . . Necessary??

[megatron_55]

Hey guys . . . Another lighting question . . . First of I have a 27 gallon tank(36x14x12 approx) . . .at the moment I am running 2x96watt PC's . . .

But FORTUNATELY I have found the lighting of my dreams for the 27gal . . . It is 2x150 watt DE 20000k MH bulbs . . . the only thing is. . doesn't come with actinics.

Are actinic lights really important? Would it bother my fish?? ALSO . . . IS THAT TOO MUCH LIGHT FOR MY TANK??

Thank u GuYs in advance
