400W MH Sufficient?

Hello All,

I have a 30g tank and plan on having mostly SPS coral and T. Clams in the tank.

Will 1 400W 10000K MH light work? Or do I need to include a PC and a Act. light?

Heck yeah that's what I'm talking about. Someone that plans for some serious lighting. Your SPS and clams will grow like crazy. Ok here's the deal, 10K will provide excellent growth but no fancy colors, 20K will have fancy neon colors but slow growth. For both you might try a 14K bulb. I'd suggest a 10K for growth and add a VHO or T5 URI super actinic to make the colors pop. The nice part is you can use the supplemental light to lower your electric bill. There would be no reason to run a halide 12 hours. Start the actinics about 2 hours ahead of the halides and turn the halide off 2 hours before the actinics. This would allow a 12 hour cycle with 8 hours of intense lighting and 4 hours of warm up and cool down. You never want to "shock" your inhabitants with that much instant light. My only concern with a 30g and that much light is that the water could get warm very fast. Remember to keep the temp under 80F. A sump will help cool water as it comes into contact with air. Placing the lamp at least 6" above the water and blowing a fan under the light/above the water will help drive the heat away. PM me for some great ideas on lighting if you have not yet purchased, I've got plenty more tips that would fill this forum end to end.

yup nice lighting for clams and SPS. I am running the 14K bulbs my self. I like the color and the growth has been good. as mike said the temp swings will be larger with that small amount of water and that much light. I would look into a chiller.

besides that you will be very happy with 1 400W
