70w DE MH bulb

[Whobe143]

I want to know what 70w bulb is best for reefs

Go for something around 12,000 - 14,000K. A lot of people seem to like this colour temperature and it provides good PAR.

Does it have actinic?

 

[Bige]

Actinic is different. The color temp he speaks of is the color from the mh. The actinic is a blue light that brings out more color.

I am obviously not to familiar with MH when it comes to wattage, color, and setup

the higher the color temp, the blue-er so 10000K is a cool white, and 12-14000K is more blue, and gives a nicer tone to reefs if thats you're style

just depends on what you like, though if you have no actinic supplement id go for a higher (~12-18000K) bulb, i know ushio makes quality bulbs

The 12,000 - 14,000K range is a nice balance of blue and white and tends to give a more crisp white without being to slanted towards a yellowy colour at the lower end of the spectrum (8,000-10.000K area) and not being to blue at the higher end of the spectrum and not giving off enough PAR for your corals to use.
