Lighting for reef tank

[Webo]

Have a 92 gallon corner tank. I purchased a Sunpod MH 36" long fixture with two 250 MH 14,000k bulbs and 18 LED moonlights. Looking to supplement the fixture with actinic lights. The tank is 24" deep. Based on the odd dimensions of the tank, I was thinking of using 1 coralife 24" T-5 double linear fixture (includes two 14watt 03 actinics) for the back of the tank; and 1 coralife 36" T-5 double linear fixture (includes two 21watt actinics) for the front of the tank. The MH fixture will be in the middle. So the total wattage for the lighting will be 500 watts (MH) and 70 watts (actinic - T-5). Will that be sufficient for lighting the reef (i.e., sps, clams and soft corals)? The coralifes have just the right width to fit on the tank and still allow the MH to effectively light tank.

Yep, looks like you have your actincs figured out rather well. I hear corners and bow fronts are hard to light in a very effective manner without shadows and shady areas.

Plenty of light, with or without the actinics

Thanks for the help. What is the benefit of the actinics, since it seems that the MH's are carrying the bulk of the lighting requirements? The actinics I'm using are not that powerful for the tank of this size (i.e., 70 watts in total). I understand I can use the actinics for pre and post MH lighting being on during the day, but what else would the benefit be?

thanks.
