Actinic Replacement

[corriewf]

I'm referring to VHO lighting: URI 2x110 superactinic-R, 2x110 10K Aquasun.

If the actinics are primarily for the benefit of providing a pleasing color and don't really provide for coral growth, do I need to replace them as frequently as the Aquasuns (every 8 months)?

The blue isnt really needed as a 65k bulb has enough blue so yes its for looks "the blue". However if your trying to stimulate a luner cycle thats different.Also the actinics do count towards your total wattage so after 6 months your output is going to be pretty low from those bulbs.

I like the growth I'm getting, so I'm going to stick with what I've got going. "If it ain't broke, don't fix it" is good for me.

Thanks for all the input and the interesting discussion. I'll definately do more in-depth study when the 175 is delivered next month. It's got 3 MH and T5's, which I haven't really studied yet. Golly gee, I'm addicted.
