That would be a good way to start up reaping the benefits of these new lights without incurring a major expense. Do figure on around 400.00 dollars though for such a 175 watt setup. The color, though, is very pleasing to the eye. Because of the fact that is strong lighting, if the surface of the tank's water is moving, you will see ripple lighting inside your tank. This gives the tank a very natural look.ion, little need to supplement this type of lighting with actinic bulbs, although doing so before and after the photoperiod, for perhaps one hour each time, is not wrong and can be done without any ill effects.
All corals open up more, although there are some exceptions.
Not all of them react positively. To do so you would not run the new lights for there full cycle right from the start, but you would sart with only a few hours a day and then gradually build up the lighting period every two to three days. Introducing the new lighting in this manner give the corals a chance to adapt to it without undue stress, and without bleaching or expelling their Zooxanthellae. All corals that require intense lighting e.g. clams, do much much better under 10 K Kelvin lighting. Several muffin fans should be present to extract the heat.
